Late Cenozoic uplift of southeastern Tibet
… continuous across the southeastern Tibetan Plateau margin and can be correlated in order to define the maximum envelope of topogra phy of the margin itself. This observation contradicts earlier notions that the low-gradient plateau margin slope (i.e. the maximum elevation of the …

Receiver function study in northeast Tibet and adjacent boundaries
As part of the NorthEast Tibetan plateau Seismic (NETS) project, we performed receiver functions analysis across the northeastern Tibetan plateau and adjacent boundaries. Using the data of about 500 events obtained from 61 broad-band stations, we provided a detailed image of the Moho geometry and …

Petrogenesis and thermal history of the Kunlun Batholith, Northern Tibet
… of the several microplates that comprise the Tibetan Plateau. Geochronological data from the Kunlun batholith defines three distinct periods of intrusion at 390 Ma, 250 Ma and 190 Ma. A model is presented whereby the Devonian intrusions are considered to be related to a collision event between …

Magmatic And Tectonic Evolution Of Southern Tibet And The Himalaya
The Himalaya-Tibetan orogen has become the paradigm for continental collision and is central to deciphering continental tectonics. Neogene extension in the orogen is not predicted by plate tectonic theory, and its significance is widely debated.<br></br><br></br>In the Himalaya, north-south …

Ambient noise interferometry and surface-wave array tomography in southeastern Tibet
… mantle structure and deformation in southeastern Tibet. To improve the resolution in the crust, we developed a new approach for surface-wave array tomography by combining inter-station phase velocity dispersion measurements from empirical Green's functions (EGFs) recovered from ambient noise …

Middle Crustal Ductile Deformation Patterns in Southern Tibet: Insights from Vorticity Studies in Mabja Dome
<p>Mabja Dome, southern Tibet, exposes mid-crustal rocks proposed to have originated from a southward flowing mid-crustal channel. Kinematic, mean kinematic vorticity (Wm), and metamorphic petrography analyses on these mid-crustal rocks were performed to test this hypothesis. Kinematic indicators …

Deformation, erosion and sedimentation in collisional orogens : case studies from eastern Tibet and southwestern China
… the gradient of crustal thicknesses from eastern Tibet southeast into Yunnan province. The second chapter provides a review of the regional geology of western Yunnan and the detailed structural geology of the region around the first bend of the Jinsha (Yangzi) river. Structures record a long …

Kinematic Evolution, Metamorphism and Exhumation of the Greater Himalayan Sequence, Mount Everest Massif, Tibet/Nepal
… low angle detachment fault above (South Tibetan detachment; STD) and by a thrust fault below (Main Central thrust; MCT). Assuming simultaneous movement on these features, the GHS can be modeled as a southward extruding wedge or channel. Channel flow models describe the coupling between …

State-of-stress and rheology of Tibet and its vicinity from gravity anomalies and numerical models
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Earth, Atmospheric, and Planetary Sciences, 1997.

Stratigraphic signatures of convergent orogenesis from the plate interior : studies from Tibet and the southern Rocky Mountains
… of orogenesis in the Qaidam basin of northern Tibet and the southern Rocky Mountain basins of North America, we provide new constraints on the timing of deformation, the development of proximal basins, and the evolution of continental-scale drainage patterns in two of the most prominent modern …

The tectonometamorphic evolution of the Greater Himalayan sequence as exposed in central Nepal and adjacent south-central Tibet
… foreland. The GHS in central Nepal and adjacent Tibet is deformed pervasively; quartz c-axis orientation fabrics from across the GHS indicate that it was deformed at high temperatures (~550-650˚C). The asymmetries of these quartz c-axis fabrics confirm field observations that define a reversal in …

Storytelling and Networking on Tibet: Relationships between narratives, framing and networks within and between two oppositional issue networks
… in two competing issue networks concerning Tibet, Tibetan refugees and the Tibet Movement: an issue network in support of the Tibet Movement and an issue network based in the People's Republic of China (PRC) that generates English language propaganda in support of the Chinese Communist …

Programmed emptiness : research infrastructure on the Tibetan plateau
… line running from central China to Lhasa in the Tibet Autonomous Region has brought attention not only to China's Architecture and Urbanism questionable occupation of Tibet, but also to the face that modernization in the TAR has adopted and the accompanying implications of China's large …

When You Find Us We Will Be Gone
… landscape; public and private conflicts in Tibet; the role of art in the Holocaust. The stories are set in America, Croatia, Japan, Germany, and Tibet, where the characters imbibe strangeness from their surroundings and in doing so chart loneliness and dissatisfaction with life.

The Limits of Empire: The Qing-Gurkha War and China’s Trans-Himalayan Frontier, 1788–1793
… trans-Himalayan frontier, its administration of Tibet, and the limits of its influence in the late 18th century. The conflict was triggered by repeated Gurkha incursions from modern-day Nepal into Tibet, which was under Qing protection. In response, the Qing launched two military campaigns, the …

Peripheral Alternatives: Media and Tibetan Nationalism in the Chinese Tibetosphere
… examines the media use in the spreading of Tibetan nationalism in the Chinese Tibetosphere, the struggling land of national politics situated between the two power centres of China and the exiled Tibet. For individual Tibetans on the ground, the small pieces and specific details in everyday …

Roots and routes : locating Tibetan identities in diaspora
Cognisant of a legacy of exotification of Tibet and Tibetans, Tibetan studies scholars have argued for a certain instrumental internalisation of romantic Western portrayals by Tibetans. Exemplifying this perspective, Lopez worries that Tibetans have been forced to perpetuate limiting orientalist …

Seismic studies of 3-D elastic and anelastic structure of crust and upper mantle in Western China
… heterogeneity, especially because of the Tibetan Plateau, the largest and highest plateau in the world, which was created by the Cenozoic Indian-Eurasian continental collision. It is seismically very active even in some populous regions. Therefore, it is important to study the crustal and …
