Pulsed exhumation of interior eastern Tibet: Implications for relief generation mechanisms and the origin of high-elevation planation surfacesReiners, Peter W., Zhang, Huiping, Oskin, Michael E., Liu-Zeng, Jing, Zhang, Peizhen, Xiao, Ping 01 September 2016 (has links)
River incision into a widespread, upland low-relief landscape, and related patterns of exhumation recorded by low-temperature thermochronology, together underpin geodynamic interpretations for crustal thickening and uplift of the eastern Tibetan Plateau. We report results from a suite of 11 (U-Th-Sm)/He cooling-age samples. Eight samples comprise a 1.2 km relief section collected from elevations up to 4800 m in the Jiulong Shan, an elevated, rugged region located in the hinterland of the Yalong-Longmen Shan Thrust Belt, and surrounded on three sides by upland low-relief landscape surfaces. Zircon and apatite cooling ages record two episodes of rapid exhumation in the early Oligocene and late Miocene, that were separated by a period of stability from similar to 30 to 15 Ma. The first episode is consistent with a similar pulse evident from the Longmen Shan. The second episode is ongoing, and when integrated with adjacent cooling-age data sets, shows that doming of the Jiulong Shan has resulted in 2 to 4 km of differential exhumation of the plateau interior. We show from a compilation of glacial landform-mapping that the elevation of the plateau surface closely tracks global last glacial maximum equilibrium line altitude. We hypothesize that smoothing of highlands by efficient glacial and periglacial erosion, coupled with potential river captures and conveyance of sediments via external drainage, can yield an apparently continuous low-relief plateau landscape formed diachronously at high elevation.

In Requiem Aeternam : monuments funéraires du littoral méditerranéen de la petite Camargue à la Catalogne du nord, XIe - XVe siècles / In Requiem Aeternam : funeral monuments of the Mediterranean coastline of "La Petite Camargue" to "Catalogne du Nord", 11th-15th centuryChauvain-Marc, Sylvie 09 December 2013 (has links)
Objet sculpté ou gravé, associant l’image et le texte, le monument funéraire se charge des aspirations spirituelles, sociales et artistiques de groupes sociaux divers. Dans un souci de préservation mémorielle, gisants, dalles à effigie, sarcophages ossuaires, bas-reliefs aux représentations diverses (funérailles, absoute, Christ de pitié, crucifixion, Vierge de la Chandeleur), tombeaux monumentaux ou épitaphes, mettent le défunt en scène au terme d’un cheminement de vie culminant à la quête du salut éternel de l’âme. Cette volonté de laisser une trace, de perpétuer son souvenir au-delà de la mort, pousse le commanditaire à mettre en ordre ses affaires, avant d’immortaliser ses derniers espoirs et ses dernières volontés dans la pierre. La grande variété typologique du territoire étudié, compris entre la Petite Camargue et la Catalogne du Nord du XIe au XVe siècle, met en évidence les traditions artistiques funéraires locales, et les apports septentrionaux et plus méridionaux (Espagne, Italie) qu’elles intègrent. Cette approche globale du patrimoine funéraire du littoral méditerranéen et de la société apporte une meilleure compréhension des mentalités religieuses, des pratiques juridiques (testaments) et économiques (dons, legs pieux, fondations de chapelles et d’anniversaires) et enfin esthétiques (somptuosité, ostentation), au seuil du trépas. Le croisement de différentes sources écrites et numériques (base Palissy) conduit à l’élaboration d’un corpus prenant en compte les monuments funéraires retrouvés, mais également disparus dont on garde traces dans les productions anciennes. / Carved ou engraved objet, associating the image and the text, funeral monument embodies the spiritual and artistic aspirations of various social groups. In order to preserve memory, recumbent statues, tombstones with effigy, sarcophagus ossuaries, low-reliefs with various representations (funeral, absolution, Christ of pity, crucifixion, Virgin of the Candlemas), monumental tombs or epitaphs, present the deceased at the end of his journey through life, peaking at the quest of the eternal salvation of the soul. This will to leave a trace, to perpetuate one’s memory beyond death, pushes the one who ordered such tombstone into putting one’s affairs in order before immortalizing his last hopes and his last wills in the stone.The large typological variety of the studied territory, between little “Camargue’ and the north of “Catalogne”, of the 11th to the 15th centuries, highlights the local funerary artistic traditions and the northern contributions or the more southern ones in Europe (Spain, Italy) which they integrate. This comprehensive approach of the funeral heritage of the Mediterranean coastline and the society brings a better understanding of religious mentalities, legal practices (wills), and economic (gifts, pious legacy, foundations of chapels and death birthdays) and lastly esthetic ones(sumptuousness, ostentation) at the threshold of the death. The crossing of various written and digital sources (Palissy bases) has led to the development of a fascinating corpus taking into account the monuments that were found again, but also the ones that disappeared, whose traces are found in the old productions.

Bounded SurfaceBrown, Emilie Sayward 01 January 2008 (has links)
The relationship between surface, perception, and structure has occupied my graduate studies. Locating, transforming, and transcending the surface requires play with perceptive abilities not only of vision, but of touch, hearing, and the other senses as well. How do the interactions of sense with the qualities of a surface determine our perception of the world? What role does the extension of the senses play in one's ability to perceive surface and structure? Using sense information gleaned from surfaces, the tectonics of our world are made visible. Might this relationship be played backwards as well? Composed structures produce surfaces upon which limina can be sensed.This written accompaniment to the thesis works is intended to continue the exploration of the surface/ sense/ structure relationship. With the visual work as a basis, each section consists of two parts. This structure is a tool for producing sense information for the viewer concerning the visual work.The first part serves as a bridge between the particular visual work and the second part. Consisting of a page or so of text, the first part of each section is also intended to set a tone or position the reader for the second part. The second part is more formal and speaks about the ideas behind the produced object, and for the most part could be applied to any works in this thesis. My desire is that the adjacency of the pieces in each section will create a friction of sorts an awareness of the surface between the two writings, and perhaps, between the writing and the objects.

Ordmånglarens Brunn Wordmonger’s WellArdelius Blane, Mercedes January 2019 (has links)
In my essay I am looking at the common heritage of written signs and images through my own experience of attention deficiency and mental illness. Through this lens of experience in which words and images are vividly transformed and merged, I am reflecting on language and art and their overlapping. Throughout the text I reference early written entirely pictorial languages, the painterly terms of thought disorders, as well as how the images that gave name to the characters in the phonetic alphabet is still lurking in the very letters themselves. I also exemplify how attention deficiency can evoke new image/text hybrids in a chapter I call ADHD poetry. In my own artistic practice I am drawn towards a melting point of language, written sign, image, high and low, illusion-representation-materiality, intellect and intuition. The surface as a physical object and idea – that there is a two-dimensional space where we project fantasies and fiction. Through prose, play, rhythm, rant, word salad, crumble of meaning etc. sandwiched, I am observing the swelling of words.
