Petrogenesis, U-Pb zircon geochronology and tectonic evolution of the Malaysian granite provinces in the Southeast Asian tin belt

Ng, Wai Pan January 2014 (has links)
The Malaysian granitoids form the backbone of the Malay Peninsula and have long been recognized as composed of two distinct granitic provinces separated by the Bentong-Raub suture zone: <table><ol><li>Early Permian to Late Triassic Eastern Province (Indochina – East Malaya) with mainly “I-type” hornblende-bearing granitoids, associated with Cu-Au deposits, and subordinate hornblende-free pluton roof-zones hosting limited Sn-W deposits; and</li> <li>Late Triassic Main Range Province, western Malaysia (Sibumasu) with mainly “S-type” hornblende-free granitoids, associated with Sn-W deposits, and subordinate hornblende-bearing granitoids.</li></ol></table> Field observations and new geochemical data suggested that the division of the Eastern Province and Main Range granitoids using Chappell and White’s (1974) I-S classification could be problematic, as there is a large degree of overlap between the two granitic provinces in terms of lithology, mineralogy and metallogenic affinity. The Main Range granitoids are more fractionated than the hornblende-bearing Eastern Province. Although the two granitic provinces were emplaced into different continental terranes, both granitic provinces exhibit common trace element geochemistry in the enrichment of high field strength elements (HFSE) and rare earth elements (REE) compared to typical Cordilleran I-S granites. Such enrichment is interpreted as an inheritance signature from the protoliths. The Kontum massif (an analogue of Indochina lower continental crust) comprises intraplate ortho-amphibolites and para-gneisses, which could serve as two hypothetical source end-members for the Malaysian granitoids. The model suggests that the geneses of the parental magmas of the Eastern Province and the Main Range Province were related to hybridization of melts derived from protoliths, geochemically and isotopically similar to these two source end-members, but in differing proportions. The fact that the granites from the two granitic provinces are so similar compositionally and metallogenically, suggests that similar protoliths were involved in their source. The incorporation of sedimentary-sourced melt makes the Main Range granitoids transitional I/S-type in nature, but this is unlikely to be true for the less evolved Eastern Province fractionated I-type granitoids. The hybridization of igneous- and sedimentary-sourced melts, and granite fractionation promotes Sn metallogenesis in the Main Range granitic province. Previous ages were obtained using whole rock Rb-Sr and biotite K-Ar geochronology in the 1970s and 1980s, dating methods that almost certainly do not accurately represent the crystallization age of granites. New ion microprobe U-Pb zircon ages are presented that provide new temporal constraints for the Malaysian granitic magmatism. Eastern Province granitoids have U-Pb zircon ages that range from 289 to 220 Ma, while Main Range Province magmatism is constrained between 227 and 201 Ma. A progressive westward younging trend is apparent across the Eastern Province, but becomes less obvious in the Main Range Province. In addition, the U-Pb zircon analysis of the Malaysian granitoids suggests that both granitic provinces have Cambro-Ordovician and Mesoproterozoic inheritance signatures, which match the ages of the Kontum intraplate ortho-amphibolites and para-gneisses, the two source end-members of the suspected Indochina basement. Two different tectonic models have been suggested to explain the formation and the emplacement of the Malaysian granitoids. Both models involve an east-dipping subduction zone during the Early and Mid-Triassic with Palaeo-Tethys lithosphere rolling back along the Bentong-Raub suture zone to produce westward younging ages in the Eastern Province granitoids. The first model (modified after Searle et al. 2012) suggests the younger Main Range granitoids were produced by another Late Triassic – Cretaceous east-dipping (Neo-Tethyan) subduction to the west of Sibumasu, after the Sibumasu – East Malaya collision. The transitional I/S-type geochemistry of the Main Range granitoids was caused by the partial melting of the more heterogeneous Sibumasu basement. The second model (Oliver et al. 2014) suggests the younger Main Range granitoids were produced by the westward underthrusting of Indochina crust of East Malaya beneath Sibumasu along the Bentong-Raub suture zone after the continental collision. In this model, the source of the Main Range granitoids was the pre-collision I-type Eastern Province granitoids. The second model is less likely, as no geological evidence for such underthrust is found in the Malay Peninsula.

SINGLE-PARENT FAMILIES IN BANGKOK, THAILAND: FACTORS AFFECTING CHILDREN LIVING IN SINGLE-PARENT FAMILIES

Jiumpanyarach, Waruesporn 01 January 2011 (has links)
There has been a transformation in family structure in Thailand due to the changes in economic and social structures over time. Though not recorded in census data the rise in single-parent families can be expected due to a rise in divorce rates, that have been recorded, over the past decades. However, the literature on single-parent families is limited and little is known about the experiences of single-mothers and children of singlemother families in Thailand. This study examines the factors that have major impacts on the well-being of children of single-parent families in Bangkok, Thailand. A qualitative methodology was employed to study the lived experiences from the point of views of 20 divorced single-mothers and 20 adult children from a different sample of divorced single-mother families in Bangkok, Thailand. Altogether 40 semistructured interviews were conducted in Bangkok, Thailand during June and July of 2010. Three theoretical frameworks, including family and household decision making theories, the life-course perspective, and the family composition perspective were applicable in this study to provide an understanding of how economic and social structures play an important role in the dissolution of marriages and how family composition plays an important role in the well-being of children. The findings of this study shed light on the lived experiences of participants and revealed the important factors that influence the well-being of children of single-mother families. The major factors include financial resources, parenting styles and discipline, and social supports. In addition, this study has implications for developing programs to assist and facilitate the well-being of single-parent families, strengthening the relationship within extended families, and eradicating the negative assumptions that are often associated with single-parent families.

The Poetry of Li-Young Lee: Identity, Androgyny & Feminism

Qualls, Barbara 01 July 1993 (has links)
In my investigation of Li-Young Lee's poetry, my concerns were two-fold: first, to find evidence of an androgynous quality or ideal; secondly, to demonstrate that ideal as authentically feminist. In the introduction, I investigate the feminist debate about the traditional definition and concept of androgyny, demonstrating the difference between the patriarchal traditional androgyny and the androgynous elements in Lee's poetry. In Chapter Two, the rose as image and as symbol in Lee's poetry is examined and found to be strikingly androgynous as a symbol. As an image, however, it is more often than not used as a vehicle to describe the destructive nature of social tyrannies such as the patriarchal symbolic order. In Chapter Three, Lee's heavy implications of an existing "other" is examined. This examination is particularly pertinent when considering the feminist debate, since one of the major problems with the idea of androgyny is that it often necessitates a binary thought system in which the male is usually the "one" and the female is usually the "other." In Lea's poetry, I found no significant evidence of that kind of phallocentricism; rather, I found substantial evidence that Lee's poetry demonstrates the destructiveness of insisting on any being's otherness. Lee's search for identity, and for the meaning of personal identity, involves the acceptance of the mutability of identity. In conclusion, although I don't find androgyny to be authentically feminist, I find Lee's poetry--and its particular use of an androgynous ideal--to be authentically feminist.

The Study of ASEAN and Cross-strait Relations in Relation with Political and Economic Development: Perspectives From Improvement of China's Image and ECFA

Lin, Shih-Chi 21 June 2012 (has links)
Since the Cold War ended with the collapse of the Soviet Union, China has become a nation that rises to strong power. While the USA, Japan, the EU and Russia marvel at China¡¦s progress and improvement, its neighboring countries in Asia were worried. They question whether the rise of China will bring about peaceful co-operation between nations or it will lead to potential threats. But China in 2005 claimed to take the path of peaceful development in order to improve the image of China. At the time the formation of the European Union, for its member countries to enjoy the advantage over import and export trade with each other, Asia also started a new union of its own, the ASEAN. Although there were negative impacts on China with Tiananmen Square Incident and poisonous milk incident, the Beijing 2008 Olympics games and the World Expo 2010 Shanghai have helped to improve the China¡¦s image which has brought the attention of the ASEAN. China signed the free trade agreement with the ASEAN in 2010 resulted in ASEAN Plus One. In addition, zero tariff trade agreement starting has further improved the development of China¡¦s economy. The Taiwanese government has signed the ECFA with China in June 2010 which relates to the development of the nation in the next ten years to a large extent. However, will ECFA really prevent the marginalization of Taiwan in the global economy or will Taiwan become more marginalized? Will China exploit the economy of Taiwan due to ECFA? Or will it help the Taiwanese economy to reach its peak? In this thesis, the theory of international relations will be examined at the global, international, local and individual levels and the analysis on the future development of the ASEAN and the Cross-strait political and economic relations of China and Taiwan from the perspectives of improving the image of China and ECFA will be carried out. The prediction of the future development of relations among the ASEAN, Mainland China and Taiwan will also be included in this research. Finally, suggestions will be provided in the conclusion for the leaders to make any future decisions on the issues discussed. It is unquestionable that most ¡§peaceful co-operation¡¨ between Taiwan and Mainland China has ever existed is happening today in the past 62 years of Cross-strait co-operation history. As such, it is hoped that the developments of both Mainland China and Taiwan can be sustained and they can co-operate to explore the resources of South East Asia.

Images of the Dai : the aesthetics of gender and identity in Xishuangbanna

Komlosy, Anouska January 2002 (has links)
This thesis is based on fieldwork carried out m Xishuangbanna Dai Autonomous Prefecture, Yunnan Province, China. The main focus of the work is the Dai people, one of China's fifty-five so called 'Minority Nationalities'. I aim to paint a picture of the complex processes through which Dai ways of being and images of them are created and recreated. This is not to suggest that the Dai constitute a bounded group. Although Chinese official discourse presents a static, rigid picture of the so-called 'Minority Nationalities', I hope to have demonstrated that the everyday experiences of those in Banna are governed by a fluid and dynamic relationality. Images of 'Minority Nationalities' abound in China, these images are multiple and often contradictory. The Dai are known throughout China for their beauty, a beauty often portrayed as highly erotic. In this thesis I explore the implications of this image and the role of the Dai in its formation and continuity. With this in mind I examine the ways that the striking Dai aesthetic is used in the intricate power plays of Xishuangbanna. This work examines aspects of the Dai lived aesthetic and as such it has chapters on tattoo, architecture and feminine beauty. Dai aesthetic knowledge is interlaced with strands of moral, philosophical and cosmological insight, thus this work also includes a chapter on morality, autonomy and cooperation. The penultimate chapter uses vivid ethnography of the Water Splashing festival as a example of play of identities in Xishuangbanna. The Conclusion reiterates that the processes by which images, identities and aesthetic understandings are generated, and by which limits are explored and transgressed in Xishuangbanna are dialogic in character.

Military Civilian Relations in Post-Revolutionary Transition: The Transformation of East Asian States and the Future of Egypt

Frazee, Amy E. 01 January 2012 (has links)
There are several theories involving civil-military relations that have been established since the Cold War. Shaped by the political transitions of Europe and Latin America, how do these theories apply to the Third Wave of democratizations? How does a more contemporary analysis of theory help understand more contemporary insurgencies such as the Arab Spring?

Provenance establishment and authentication of South-East Asian ceramics using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

Bartle, Emma Kathleen January 2009 (has links)
[Truncated abstract] The sale of fraudulent South-East Asian ceramics constitutes a large proportion of the illegal artefact and antique trade and threatens to undermine the legitimate international market. The sophistication and skill of forgers has reached a level where, using traditional appraisal by eye and hand, even the most experienced specialist is often unable to distinguish between a genuine and fraudulent piece. In addition, the current scientific method of authentication used by the international antiques and art industry, thermoluminescence (TL) dating, carries severe limitations. The technique has an error margin of +/-20 % and requires the removal of a significant piece of the sample being tested, which decreases both the monetary and cultural value of the artefact. Of more concern, forgers have developed methods which produce false test results and which appear to corroborate false claims for the age of artefacts. Consequently, the use of TL dating for authentication of ancient ceramics, especially those of South-East Asian origin, has now come into serious question. The most suitable method for authenticating ceramics is through provenance establishment. Studies published in the literature have investigated the application of various analytical techniques to provide this information for ceramic wares and have highlighted their potential to be used for provenance establishment. However, the value of each of these techniques is limited rendering them generally unsuitable for practical use in the international antiques and art world to authenticate high-value South-East Asian artefacts. Consequently, there is a desperate need for the development of a robust, accurate and non-destructive method which can be practically applied in the industry to authenticate South-East Asian ceramics. ... Minor variations between spectral profiles of artefacts produced in the same country have also been used to further provenance artefacts to a specific production region or kiln site. The results of analyses have been compiled to form a unique reference database which can be added to in the future and used by experts internationally. Adaptation of the developed sampling and analytical methodologies to allow in-situ sampling of large artefacts using the

Syncretic Souvenirs: An Investigation of Two Modern Indian Manuscripts

Helland, Madeline 01 January 2018 (has links)
The objective of this project was to establish a provenance for two Indian manuscripts that were recently discovered in the collections at Scripps College. Based on their illuminations, script, and binding structure, I was able to conclude that these two manuscripts are Hindu religious texts created around the 19th or 20th century. To determine an approximate origin and the significance of these volumes, my research focused on the syncretism of religion, material history, and power dynamics in India. Their context was specifically framed within the history of manuscript construction and conservation.
