[en] WINNICOTT AND THE AESTHETIC DIMENSION OF CONTEMPORARY PSYCHOANALYSIS / [pt] WINNICOTT E A DIMENSÃO ESTÉTICA DA PSICANÁLISE CONTEMPORÂNEA

MARTA GASPAR VIANA MOSLEY 14 July 2017 (has links)
[pt] A presente dissertação de mestrado procurou investigar a relevância da dimensão estética na teoria e na prática psicanalíticas contemporâneas a partir de experiências sensíveis e sensoriais, onde corpo e afeto comparecem como aportes clínicos fundamentais dentro do setting analítico. Partindo da teoria do desenvolvimento emocional de Donald Winnicott e de seus conceitos relativos ao ambiente, ao manejo e aos cuidados com o bebê; assim como dos conceitos ferenczianos de tato, empatia e sensibilidade, apontaremos a importância da dimensão estética (sensível) para a clínica psicanalítica contemporânea que se depara com o desafio do surgimento de novas patologias. / [en] This thesis aims to investigate the relevance of the aesthetic dimension in the theory and practice of contemporary psychoanalysis. It takes as its starting point the sensitive and sensory experiences where body and affection bring about fundamental clinical contributions to the setting. Starting from Donald Winnicott s theory of Emotional Development and his concepts about Environment , Holding and Handling of the infant, and on Sandor Ferenczi s ideas of tact, empathy and sensitivity, we indicate the relevance of the aesthetic dimension in the contemporary psychoanalytic clinic that faces the challenge of new pathologies.

[en] THE ATTACKS ON THE SETTING IN BORDERLINE PATIENTS AS A WAY TO REACH THE USE OF AN OBJECT / [pt] OS ATAQUES AO ENQUADRE NOS CASOS-LIMITE ENQUANTO TENTATIVAS DE PASSAGEM PARA O CAMPO DO USO DO OBJETO

CAROLINA PAIXAO DE ALBUQUERQUE PINHEIRO 08 November 2013 (has links)
[pt] A dissertação consiste numa pesquisa teórica que propõe o argumento de os ataques ao enquadre, frequentemente empreendidos pelos casos-limite, constituírem a tentativa clínica de passagem para o campo do uso do objeto. A agressividade não bem manejada pelo ambiente prejudica o reconhecimento da externalidade, resultando numa tendência à destruição que se torna característica central da clínica com estes casos. O trabalho do negativo malsucedido impossibilita a construção do espaço da ausência no psiquismo, fundamental à construção de representações, à instauração das fronteiras intrapsíquicas e intersubjetivas e ao investimento em objetos substitutos. Os prejuízos relativos à agressividade e ao trabalho do negativo redundam na precariedade das fronteiras entre o eu e o outro, sugerindo a prevalência de uma relação pautada na vertente subjetiva do objeto, logo não reconhecido em sua natureza externa. As contribuições de Winnicott e Green fundamentam nossa hipótese de que a destrutividade – expressa na clínica dos casos-limite através dos ataques ao enquadre – consiste numa tentativa atuada de passagem para o campo do uso do objeto, que consolida a unidade do self ao mesmo tempo que possibilita o reconhecimento do objeto na realidade compartilhada. / [en] The dissertation consists of theoretical research proposing the argument that the attacks on the setting, often undertaken by borderline patients, consists on a clinical way of reaching the use of an object. The aggressiveness not well handled by the environment affects the recognition of the externality, resulting in a tendency towards destruction which becomes the central feature in the borderline clinic. The unsuccessful work of the negative precludes the construction of an absence space in the psyche, fundamental to the construction of representations, the introduction of intrapsychic and intersubjective borders, as the investment in substitute objects. Losses related to aggressiveness and the work of the negative result in precarious boundaries between self and other, suggesting the prevalence of a relationship based in the subjective aspect of the object, not just recognized in his external nature. The contributions of Winnicott and Green underlie our hypothesis that the destructiveness – expressed in borderline clinic through the attacks on the setting – consists in an actuated way to reach the use of the object, which consolidates the unity of self while enables the recognition of the object in shared reality.

"Mafija kaip Italijos (savi)įvaizdžio dalis. Italijos dienraščių analizė" / "Mafia like a part of the (self)image of Italy. Italian daily analysis" / "Mafia come parte dell'(auto)immagine d'Italia. L'analisi dei quotidiani italiani"

Širvytė, Gražina 16 June 2008 (has links)
Bet koks nusikalstamas plačiai paviešintas įvykis ar reiškinys daro neigiamą įspūdį apie šalį – prisideda prie neigiamo šalies įvaizdžio kūrimo. Tačiau vienareikšmiškai neigiamai vertinti tokį istoriškai ir kultūriškai Italijos tapatybėje įsišaknijusį fenomeną kaip mafija, yra neteisinga. Šio tyrimo tikslas - remiantis Šiaurės, Pietų bei centrin��s Italijos dienraščių straipsnių mafijos tema kiekybine, kokybine bei žanrine analize, o taip pat mokslinės literatūros šaltinių analize, ištirti mafijos fenomeno pateikimą Italijos dienraščiuose kaip vieną iš Italijos įvaizdžio ir saviįvaizdžio formavimo prielaidų ir atskleisti skirtinguose dienraščiuose matomus minėto fenomeno įtakos skirtumus Italijos įvaizdžiui bei saviįvaizdžiui atskirose šalies dalyse. Tyrimo tikslas lemia ir tyrimo objektą, kuris yra straipsniai apie mafiją Italijos dienraščių „Corriere della Sera“, „La Repubblica“ ir „Il Mattino“ 2007 metų numeriuose. Tyrimo hipotezė teigia, jog būdama šalies identiteto dalis, mafija Italijos saviįvaizdžiui nedaro apčiuopiamos įtakos, tačiau dėl mafijos egzistavimo kenčia šalies įvaizdis, pozicionuojamas itališkoje spaudoje. Darbe atskleisti Italijos medijų sistemos ypatumai ir aptarta spaudos vieta Italijos medijų sistemoje; pristatyta agenda setting teorijos reikšmė šalies įvaizdžio kūrimui(si) bei tyrimui; identifikuota identiteto svarba šalies įvaizdžio ir saviįvaizdžio formavimui(si); apžvelgti Italijos įvaizdžio kūrimo ypatumai ir pristatyti ankstesni tyrimai...

The main sources for this thesis are the articles concerning mafia published in the Italian dailies “Corriere della Sera”, “La Repubblica” and ��Il Mattino” covering the period from the 1st of January, till the 31st of December, 2007. It was hypothesized that being a part of the state’s identity, mafia doesn’t have tangible influence on Italian self image but because of its existence, the dailies positioned image of the State is negatively influenced. Content analysis quantitative and qualitative, genre analysis and scientific literature analysis methods were used for the research. The hypothesis was proven and some other facts regarding an image and a self image of Italy were discovered. / Ogni crimine ampiamente proclamato fa un effeto negativo sull’immagine dello stato. Il fenomeno mafioso, per il suo impatto storico e culturale all’idenità italiana, non può essere considerato come solamente negativo. L’obbiettivo di questa ricerca è, basandosi sull’analisi quantitativa, qualitativa, generica, degli articoli sulla mafia dei quotidiani, rappresentanti le diverse parti – Nord, Sud e Centrale – dell’Italia, e anche sull’analisi della letteratura scientifica, esaminare la rappresentazione del fenomeno mafioso come una premessa della formazione dell’immagine e dell’(auto)immagine d’Italia nelle parti diverse del paese. L‘oggetto della ricerca sono gli articoli sulla mafia pubblicati nei quotidiani „Corriere della Sera”, „La Repubblica” e „Il Mattino” nel 2007. L‘ipotesi della ricerca suppone che essendo una parte dell’identità dello stato, la mafia non ha un impatto significativo all’immagine d’Italia. Ma l’esistenza del fenomeno, fa un effetto negativo sull’immagine dello stato che viene posizionato nella stampa italiana. In questa ricerca sono stati rivelati le particolarità del sistema massmediatico italiano; presentata l’importanza della teoria dell’agenda setting per la costruzione e la ricerca dell’immagine di uno stato; identificata l’importanza d’identità per la formazione dell’immagine e dell’autoimmagine dello stato; presentate le particolarità della creazione dell’immagine d’Italia e le altre ricerche fatte su quell’immagine; definito il termine e...

Cidade e identidade: discursividades imag?tico-espaciais e a constru??o da identidade espacial do Recife, Veneza Brasileira

Lins, Juarez Nogueira 22 June 2011 (has links)
Made available in DSpace on 2014-12-17T15:07:12Z (GMT). No. of bitstreams: 1 JuarezNL_TESE_parcial.pdf: 3587354 bytes, checksum: f627c2907f745b422a611dc049ea050d (MD5) Previous issue date: 2011-06-22 / This treatise analyzes the identitary setting called Veneza Brasileira (Brazilian Venice) which is subscribed to the discoursive materialization related to the imagetic setting (literary and mediatic) produced about the city of Recife. The main investigation of this research is to examine the way how the identitary setting called Veneza Brasileira has been constructed in the imagetic setting practices about the city of Recife in the nineteenth and twentieth centuries. This study is subscribed to the Applied Linguistics and considers the theoretical perspectives that come from the Cultural Studies which investigation basis is focused on authors such as: Hall (2006); Bauman (1999; 2001;2005); Silva (2000); and Castells (2000) related to the discussion over identity, as well as the discussion over Urban Studies presented in Santos (1997; 1999); Ferrara (1998); and Pesavento (2001). Moreover it is also based on the theoretical basis found in Foucault (2004; 2006; 2007). Furthermore theoretical-methodological approaches rely on the French Discourse Analysis (DA) found in Orlandi (2001); Gregolin (2007); and Courtine (2006). On being so, this treatise aims to: analyze the meaning effects over the production of the identitary setting, especially the so-called Veneza Brasileira, in the imagetic setting discoursive practices (Poems, Post Cards and Touristic Guides) which are produced over the urban setting of the city of Recife. This research is characterized by being qualitative and interpretative and the theoretical analytical approaches contributed to the reading of both poetic and iconic images presented in the excerpts of poems from the nineteenth century and early twentieth century in: Manuel Bandeira s poems, Carlos Pena Filho s poems, and Jo?o Cabral de Melo Neto s poems which were produced in the early and late twentieth century. Moreover, this study observed some photographic images in Post Cards and Touristic Guides related to the visiting of historical sites in Recife. One could conclude that the imagetic setting discourse about Recife produced different identitary effects over the so-called Veneza Brasileira along these three centuries: in the nineteenth century, the poetry constructed the utopia city along with the meaning effect of identitary unit; as for the twentieth century, one observed an oscillation between a utopia/heteroutopia city meaning effect of both united and fragmented identity, the latter one is prevalent. As for the twenty-first century, the media reconstructed over again the utopia city, and consequently, produced meaning effect of identitary unit. These same meaning effects of identity either corroborate or contradict to/with the concepts of the postmodernism over identity along these three centuries. In other words, considering the imagetic setting, this oscillation occurs in the proportion of one finds an (ex) inclusion of social agents that construct these same identities. / Esta pesquisa tem como objeto de estudo a identidade espacial Veneza Brasileira, inscrita nas materialidades discursivas imag?tico-espaciais (liter?rias e midi?ticas) produzidas sobre a cidade do Recife. A quest?o central que orienta a pesquisa ?: de que modo foi constitu?da nos s?culos (XIX, XX) e ? constitu?da hoje, no s?culo (XXI) a identidade espacial Veneza Brasileira nas pr?ticas imag?tico-espaciais sobre a cidade do Recife? Inscrita na ?rea de Ling??stica Aplicada esta pesquisa se vincula ? perspectivas advindas dos Estudos Culturais e articula investiga??es de Hall (2006), Bauman (1999,2001, 2005), SILVA (2000), Castells (2000) acerca de identidade a dos Estudos Urbanos Santos (1997, 1999), Ferrara (1998), Pesavento (2001) e teoriza??es foucaultianas (2004, 2006, 2007). Recorre-se ainda a alguns pressupostos te?rico-metodol?gicos da An?lise de Discurso Francesa (AD), Orlandi (2001), Gregolin (2007) e Courtine (2006). Define-se como objetivo da pesquisa: analisar os efeitos de sentidos da produ??o de identidades espaciais, em especial a Veneza Brasileira em pr?ticas discursivas imag?tico-espaciais (Poemas, Cart?es Postais e Guia Tur?stico) produzidas sobre o espa?o urbano da cidade do Recife. A pesquisa ? de natureza qualitativa interpretativista e os dispositivos te?ricos anal?ticos subsidiaram gestos de leitura de imagens po?ticas e ic?nicas presentes em fragmentos de poemas do s?culo XIX e 1? metade do S?culo XX, em poemas de Manuel Bandeira, Carlos Pena Filho e Jo?o Cabral de Melo Neto produzidos na 1? e 2? metade do s?culo XX e tamb?m imagens fotogr?ficas de Cart?es Postais e do Guia Tur?stico para Visita??o a Locais Hist?ricos do Recife. Conclui-se que os discursos imag?tico-espaciais sobre o Recife produziram diferentes efeitos identit?rios sobre a Veneza Brasileira durante esses tr?s s?culos: no s?culo XIX, a poesia construiu a cidade ut?pica e o efeito de sentido de unidade identit?ria; j? no s?culo XX, oscilou entre a constru??o da cidade ut?pica/heterot?pica efeito de unidade e fragmenta??o identit?ria, esse ?ltimo prevalecendo. E, no s?culo XXI, a m?dia reconstituiu novamente a cidade ut?pica e, conseq?entemente, efeitos de sentido de unidade. Estes efeitos de sentido identit?rios, ao longo destes tr?s s?culos ora corroboram ora contrariam a concep??o de identidades das teorias p?s, ? medida que, nas pr?ticas imag?tico-espaciais, ocorre a (ex) inclus?o dos agentes sociais que tamb?m constroem essas identidades.

Getting the audience's attention by going viral : A case study on Sverige för UNHCR’s video messages on the refugee crisis

Adamsson, Niklas, Axner, Tom January 2016 (has links)
Denna studie argumenterar för att dagens mediesamhälle fungerar som en hybrid, där sociala medier och traditionella medier lever och verkar i symbios. Det som får tillräckligt stor spridning på sociala medier kan påverka nyhetsdagordningen och därmed vad allmänheten anser vara viktigt för tillfället. Detta är betydelsefullt för biståndsorganisationer som, för att kunna nå ut till många och öka chanserna till att samla in pengar, är i behov av att deras sak får plats på dagordningen. Studien baseras på en kvantitativ innehållsanalys av samtliga publicerade videoklipp av Sverige för UNHCR på Facebook under 2015. Variablerna baserades på teorier om viralitet, som ursprungligen har utvecklats inom marknadsföring. Där ingick teori om social delning av känslor, social nätverksteori, self-determination theory samt marknadsföringsmodellen ”the Dragonfly effect”. Studien visade hur teorierna kunde utnyttjas även i detta sammanhang, om de anpassades utifrån kontexten. Resultatet visade att the Dragonfly effect tycks vara en lämplig modell i denna kontext. Videon ”Search for Syria” utmärkte sig i detta urval, genom att ha högst antal visningar kombinerat med en förhållandevis hög andel användarresponser, som bidrar till spridningen. Alla fyra steg inom Dragonfly-modellen kunde identifieras i denna video, vilket indikerar att detta är en lämplig modell för att öka chansen till spridning i denna kontext. Studien fann också att urvalet av videoklipp generellt inte var konstruerade på ett sätt som uppmuntrar till spridning. Vidare noterades att starka känslomässiga inslag, så som provokativa och obehagliga scener, förekommer mer i videor som fått flest visningar. Samtidigt tycks videoklipp med en större andel positiva och hoppfulla inslag få större användarrespons i form av ”gillningar”, kommentarer och delningar.

"Help, everybody's struggeling with what this is?" : En innehållsanalys av Diane Sawyers framställning av Bruce Jenner / "Help, everybody's struggeling with what this is?" : A content analysis of Diane Sawyers depiction of Bruce Jenner

Tolinsson, Sara, Eriksson, Hanna January 2016 (has links)
The American society is dominated by a heterosexual powerstructure with norm-filled social values. It is difficult for norm-breaking humans who live outside of the gender stereotypical social model, this includes the group of transgenders. The renowned olympic decathlon athlete Bruce Jenner, also known from the TV-series Keeping Up with the Kardashians, came out as a transgender woman in April, 2015, which aroused a great news reporting. This is a qualitative content analysis with the aim to examine Diane Sawyer’s depiction of Bruce Jenner during the interview in the TV-show ABC 20/20. Sawyer is a prominent mediaprofile in the USA and got sole rights to make the last interview with Bruce Jenner before he transitioned to become a woman. We based our method out of the symptomatic reading to understand the underlying message of the questions asked in the interview and have used Selby and Cowdery's three-stage model as an analysis tool when we created our analysis framework. Furthermore, we have applied this analysis schedule on selected key scenes that we transcribed from the interview in order to get answers to our thesis questions. The result of our thesis is that Sawyer has steered the questions asked in the interview, how they are formulated, and through it controlled the depiction of Jenner in the program. Sawyer questions to Jenner was sometimes chareterized by ignorance and prejudice for transgender, however the overall impression of the interview is that she depicted Jenner in a way that was positive and advantageous for him.

Journalistiken förändras : En kvantitativ innehållsanalys av hur mycket textreklam som finns i tre svenska lokaltidningar

Andersson, Anton, Urborn, Christoffer January 2016 (has links)
Problem definition and purpose: The media industry is a sphere faced with constant challenges. Technological inventions and economy are changing the rules of how and what media reports. To be able to stay current and make profit the newspapers have to adapt new thinking and evolve. In Sweden the journalistic union have stated that the line between editorial material and advertisement has became thinner. The purpose of this study is therefore to examine the state of three local newspapers today and the ten years back. It will examine if the occurence of what can be define as advetorial news – articles made by the newspapers own reporters but which serve and obvious profit for a second part – has increased or decreased. Method and material: To find an answer to the purpose of this thesis a quantitative content analysis have been done on a total of 1005 local news articles from three Swedish local newspapers in 2005 and 2015. Main result: The result of the content analysis shows that news defined as advetorial occur more frequently in two of the three studied news papers 2015 compared to 2005, while news defined as advetorial decreased in one of the news papers. The result also show that the total number of local news articles has decreased from 2005 to 2015.

Ink film splitting acoustics and tack on paper in offset printing

Voltaire, Joakim January 2004 (has links)
<p>This licentiate thesis comprises two complementary studiesdealing with the sheet-fed offset printing of paper. The firststudy addresses the further development of a practical methodto acoustically monitor and analyse the film splitting ofoffset inks. This method was tested on laboratory printingequipment, specifically monitoring the continuous ink splittingin the nip of an IGT ink distribution unit and the short-timeink splitting in the inked print disc-paper nip of the printingunit of an ISIT instrument. The study verified that the inksplitting component of the acoustic signal contributes to thehigher frequency range (10-20 kHz) of the audible spectrum, andcan thus be separated from the lower frequency machine noise.Furthermore, the film splitting component is sensitive tochanges in the ink and printing conditions, thus enabling itsuse in probing the fundamental mechanisms occurring during inktransfer and also suggesting its applicability fornon-intrusive monitoring of industrial printing presses. Anincrease in film thickness during ink distribution correspondsto an increased acoustic power, with the exception of very lowink amounts, which give reduced acoustic emission due to alubricating effect. The effect of the presence of fountainsolution was simulated by adding emulsion-forming, butnon-evaporative, ethylene glycol. This produces an increase inacoustic power at low amounts, due to resistance to glycol dropdeformation, followed by a decrease at higher amounts owing toexcess glycol lining the rolls. During test printing on paper,increasing ink amounts also display an increased acousticresponse.</p><p>The second study further developed a theoretical model toexplain and predict the evolution of ink tack in terms of inksetting directly after offset printing on coated paper. Asmeasured by the ISIT, the tack of the printed ink rises duringshorter time periods, attains a maximum, and then falls atlonger times. The proposed model described how the ink tack,characterised by the impulse during disc pull-off, dependsdynamically on the viscoelastic properties of the ink, thecontact with paper and disc, and the flow geometry. The inksetting was modelled as a diffusion-limited transport of theoil vehicle through the ink film and into the pores of thecoated paper. The coupling of the tack and setting models,compared to the ISIT experimental measurements, then provided adiffusion coeffcient for ink setting during the tack riseperiod. This coeffcient decreases with time, and increasinglyrapidly with decreasing ink amounts due to theconcentration-dependent diffusion. For an accurate descriptionthe elasticity and adhesion effects also have to be considered,at least for explaining the tack fall period.</p>

Provenance Analysis of the Sperm Bluff Formation, southern Victoria Land, Antarctica

Savage, Jeni Ellen January 2005 (has links)
Beacon Supergroup rocks of probable Devonian age, containing conglomerate clasts of lithologies unknown in outcrop in southern Victoria Land (SVL) occur in the St Johns Range to Bull Pass Region, SVL, Antarctica. The Lower Taylor Group sedimentary rocks, herein called the Sperm Bluff Formation, unconformably rest on the regionally extensive Kukri Erosion Surface that truncates local basement. The basement complex includes three Plutonic Suites, Dry Valley (DV) 1a, DVIb and DV2 of the Granite Harbour Intrusives that intrude metasedimentary rocks of the Koettlitz Group. Allibone et al. (1993b) suggested a SVL terrane accretion event may have occurred about the same time as accretion of a terrane known as the Bowers terrane in northern Victoria Land (NVL) based on changing chemistry of the CambroOrdovician granitoids. Further, it is suggested that conglomerate clasts of the Sperm Bluff Formation may have been derived from this postulated terrane (Allibone et al., 1993b; and Turnbull et al., 1994). Following extensive fieldwork provenance studies and basin analysis of the sedimentary Sperm Bluff Formation are used here to test these ideas. The Sperm Bluff Conglomerate of Turnbull et al. (1994) is re-interpreted as the Sperm Bluff Formation and described using a lithofacies-based approach. The Sperm Bluff Formation is divided into six lithofacies including 1) Conglomerate Lithofacies; 2) Pebbly Sandstone Lithofacies; 3) Crossbedded Sandstone Lithofacies; 4) Parallelbedded Lithofacies; 5) Low-angle Crossbedded Lithofacies; and 6) Interbedded Siltstone/Sandstone Lithofacies. The intimate field association of the Conglomerate, Pebbly Sandstone and Crossbedded Sandstone Lithofacies ties them to the Conglomerate Lithofacies Association whereas the other three units are independent. The Conglomerate Lithofacies Association is interpreted to represent a wavedominated deltaic environment, based on the presence of broad channels, pervasive crossbedding, paleocurrent and trace fossil data. Both Parallel-bedded and Low-angle Crossbedded Sandstone Lithofacies are interpreted as a foreshore-shore face shallow marine setting on the basis of low-angle crossbeds and trace fossil assemblages. The Interbedded Siltstone and Sandstone Lithofacies is interpreted as an estuarine environment based on alternating siltstone/sandstone beds and the presence of flaser and lenticular bedding, small crossbedded dune sets, mud drapes, syneresis cracks and diverse paleocurrent directions. An estuarine setting is tentatively favoured over a lagoonal setting due to the presence of syneresis cracks small channels and the proximity to a river delta. I suggest that the Sperm Bluff Formation is likely a lateral correlative of the Altar Mt Formation of the Middle Taylor Group, in particular the Odin Arkose Member. This interpretation is based on arkosic nature of the sedimentary rocks, regional paleocurrent patterns, the presence of salmon pink grits at Gargoyle Turrets and trace fossil assemblages. The upper most lithofacies at Mt Suess, the Low-angle Crossbedded Sandstone Lithofacies that only occurs at this site is- suggested as a lateral correlative to the Arena Sandstone, which stratigraphically overlies the Altar Mt Formation, based on quartzose composition, clay matrix, stratigraphic position and trace fossils present. Provenance analysis was carried out on sedimentary rocks and conglomerate clasts using clasts counts of conglomerates, petrographic analysis of clasts, point counts of sandstones and clasts, geochemistry and V-Pb detrital zircon analysis. Conglomerate clasts lithologies include dominantly silicic igneous clasts and finely crystalline quartzite clast amongst other subordinate lithologies such as vein quartz, schist, schorl rock, gneiss and sandstone. Despite past identification of granitoid clasts in the Sperm Bluff Formation (Turnbull et al., 1994), none were found. Rhyolitic clasts of the Sperm Bluff Formation have compositions typical of highly evolved subduction related rocks, although they have undergone post-emplacement silicification. Wysoczanski et al. (2003) date rhyolite and tuff clasts between 497±17 Ma and 492±8 Ma, placing them within error of all three Dry Valley Magmatic Suites and removing the likelihood of correlation to NVL volcanic rocks. Petrographic analysis suggests they are components of a silicic magmatic complex. Chemically the volcanic clasts appear to represent a single magmatic suite (Sperm Bluff Clast Suite), and are clearly related to the Dry Valley Plutonic Suites. Although clasts are not constrained beyond doubt to one Suite, DV2 is the best match. Quartzite clasts of the Sperm Bluff Formation are too pure and old to be derived from a local source. Detrital zircon V-Pb ages for the quartzite suggest zircons were derived from the East Antarctic Craton, and that the quartzite source rocks were deposited prior to the Ross-Delamarian Orogeny. Quartzite with a similar age signature has not been identified; however, the Junction Formation sandstone of northwest Nelson has a similar age spectrum. Sandstones from the Sperm Bluff Formation indicate derivation from a felsic continental block provenance, which contain elements of volcanic, hyperbyssal and plutonic rocks. They are arkosic to quartzose in composition and conspicuously lack plagioclase. Detrital zircon analyses give a strong 500 Ma peak in all 3 samples, characteristic of a Ross-Delamarian Orogen source, with few other peaks. The dominance of a single peak is highly suggestive oflocal derivation. The sedimentary rocks of the Sperm Bluff Formation are interpreted to be derived predominantly from the basement rocks they now overlie. The presence of the regionally extensive Kukri Erosion Surface at the lower contact of the Beacon Supergroup rocks implies an intermediate source must have existed. This most likely contained all components of the formation. I suggest that the DV2 Suite was emplaced in a subsiding, extensional intra-arc setting. Erosion of the uplifted arc region probably occurred from Late Ordovician to Silurian times with deposition of sediments in a subsiding intra-arc basin. Erosion of the rhyolitic complex in this region probably occurred, however, it is likely that some was preserved. Inversion of this basin prior to the Devonian probably provided the means for these sediments to be deposited as the Sperm Bluff Fonnation.
