The Lopu Range, located similar to 600km west of Lhasa, exposes a continental high-pressure metamorphic complex beneath India-Asia (Yarlung) suture zone assemblages. Geologic mapping, 14 detrital U-Pb zircon (n=1895 ages), 11 igneous U-Pb zircon, and nine zircon (U-Th)/He samples reveal the structure, age, provenance, and time-temperature histories of Lopu Range rocks. A hornblende-plagioclase-epidote paragneiss block in ophiolitic melange, deposited during Middle Jurassic time, records Late Jurassic or Early Cretaceous subduction initiation followed by Early Cretaceous fore-arc extension. A depositional contact between fore-arc strata (maximum depositional age 971Ma) and ophiolitic melange indicates that the ophiolites were in a suprasubduction zone position prior to Late Cretaceous time. Five Gangdese arc granitoids that intrude subduction-accretion melange yield U-Pb ages between 49 and 37Ma, recording Eocene southward trench migration after collision initiation. The south dipping Great Counter Thrust system cuts older suture zone structures, placing fore-arc strata on the Kailas Formation, and sedimentary-matrix melange on fore-arc strata during early Miocene time. The north-south, range-bounding Lopukangri and Rujiao faults comprise a horst that cuts the Great Counter Thrust system, recording the early Miocene (similar to 16Ma) transition from north-south contraction to orogen-parallel (E-W) extension. Five early Miocene (17-15Ma) U-Pb ages from leucogranite dikes and plutons record crustal melting during extension onset. Seven zircon (U-Th)/He ages from the horst block record 12-6Ma tectonic exhumation. JurassicEocene Yarlung suture zone tectonics, characterized by alternating episodes of contraction and extension, can be explained by cycles of slab rollback, breakoff, and shallow underthrustingsuggesting that subduction dynamics controlled deformation.

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.

This study traces the development of Tibetan 'treasure' texts and practices in contemporary times via the life-story and scriptural revelations of the Tibetan 'treasure revealer' (gter ston) Kun bzang bde chen gling pa (1928-2006). It examines how his revelations (gter ma) rooted in the historic spirituality of Tibet, continue and adapt into the twenty first century. The study is important in order to understand the ways this Asian religious concept develops and coalesces in North America. With the dramatic advances in communication through digital technology, it examines how gter ma texts and practices reach a modern audience. Also discussed are the implications of centuries old debates surrounding Buddhist lineage, transmission and ‘authenticity’ as well as concepts such as liberty, equality and authority. All of which are culture-specific constructions that differ radically when seen from a variety of perspectives. The main conclusion drawn from this research is that as a Western Vajrayāna ‘tradition’ emerges and intersects with older Tibetan forms, both must attempt to find a middle path between their differing applications and interpretations if they are to avoid drifting into an arena of extensive commercialisation, dilution and distortion.

The Development of Tibetan Cultural and Religious Identity among Tibetans Living outside of Historical Tibet The topic of my thesis was to find out changes in Tibetan society inside Tibet and in Tibetan exile in last 50. years and how do changes help to progress social capital. Inside Tibet is problem with high percent of nonliterary and high percent of incoming Han people, which cause that Tibetan people are getting on the edge of society, because they didn't have developed their human potential. The main problem is that Tibetan people don't know Chinese language well and this language is becoming more useful for daily life in Tibetan autonomous region. Tibetans, who are very religious, don't have opportunity to practice Tibetan Buddhism under communistic rule of Chine. Tibetans have to renounce His Holiness dalajlama and deny part of their Tibetan identity. Those reasons influence them to escape into exile. The second part of my thesis is concerned to describe push and pull factors of migration. As I found in materials, the main reasons to escape into exile were political, religion, education, economical problems and renounce dalajlama. In my research, Tibetan didn't divide those reasons to those categories, because they think of those problems in holistic way. The last part of thesis in...

The subject of this thesis is self-immolation in Buddhist countries. The author shows examples from both history and the present and interprets them as a ritualised pattern passed on from the fourth century until the present time, the continuity of which was based on literary tradition as well as on historical occurrences. She demonstrates that self-immolations in Vietnam and Tibet also follow the centuries long tradition and prove to have the same components. The author intends to answer the question of the origin of the tradition in Buddhism and its broad popularity compared to other forms of self-sacrifice. Reasons for self-immolations among the Buddhists might have been manyfold: to demonstrate their loyalty to the buddhist doctrine and the Buddha, to use it as means of attaining enlightment immediately or as a form of a political protest. All of the above can be understood as a sacrifice to the Three Jewels of Buddhism, i.e. the Buddha, the Drarma and the Sangha. The author also handles self-immolation in Buddhism as a question of ethics in order to present the problem in its completeness. In doing so, she concentrates on the point of view of the followers of Buddhism themselves. The phenomenon proves to have many forms and therefore even the Buddhists are nor united in their opinions....

Esta tese tem como objetivo a análise de fontes escritas nos contextos das missões jesuítas estabelecidas na corte mogol e no Tibete. Abordamos também a presença da Ordem em Bengala, tecendo relações entre esse espaço e as missões supracitadas. Nosso recorte cronológico cobre o período de 1570 até 1721, isto é, iniciamos nossas investigações na década que antecede o estabelecimento dos religiosos na corte de Akbar, e encerramos nossas análises no ano em que Ippolito Desideri deixa Lhasa. Concentramo-nos principalmente na questão da necessária relação entre as estratégias de conversão adotadas nessas missões e a (re) elaboração de categorias que indicassem e respaldassem o diálogo, a persuasão e o convencimento como os mais prudentes métodos catequéticos / In this thesis, we aim to analyze written sources produced by jesuits stablished at the Mughal court and in Tibet.

In contrast to the oceans, deformation in the continental lithosphere is distributed over broad regions. This dissertation is composed of three separate but related studies investigating the kinematics and dynamics of such deformation. The first two studies look at the Makran subduction zone, and the third focusses on deformation in South East Tibet. The first study is an investigation of the 11 May 2013 M w 6.1 Minab earthquake which occurred at the western end of the Makran subduction zone, adjacent to the transition to continent-continent collision in the Zagros mountains. Seismological, geodetic and field results are used to study the source parameters and slip distribution of this earthquake, and demonstrate that the earthquake was left-lateral and occurred on a fault striking ENE–WSW; approximately perpendicular to previously studied faults in the adjacent Minab-Zendan-Palami fault zone. Geological and geomorphological observations of similar faults in the vicinity are used to infer that vertical-axis rotations allow a series of such faults to accommodate ∼15–19 mm/yr of N–S right-lateral shear. The dynamic implications for the transition between subduction and continental collision are discussed. The second study looks at the Makran region as a whole. First, the shape and depth of the interface with the Arabian plate is constrained by modelling the depths and mechanisms of earthquakes across the region, and combining these with additional seismological constraints. These constraints on the subduction interface are used to investigate elastic strain accumulation on the megathrust in the western Makran, which has important implications for seismic and tsunami hazard in the region. Second, the kinematics at the northern edge of the Makran accretionary prism are investigated using a combination of geodetic and geomorphological observations, addressing the long-standing tectonic problem of how the right-lateral shear taken up by strike-slip faulting in the Sistan Suture Zone in eastern Iran is accommodated at the zone’s southern end. Finally, the kinematics and dynamics of the accretionary prism are investigated. By considering the kinematics of the 2013 Balochistan and Minab earthquakes, local gravitational and far-field compressive forces in the Makran accretionary prism are inferred to be balanced. This force balance allows the mean shear stress and effective coefficient of friction on the Makran megathrust to be calculated, 5–35 MPa and 0.01–0.03 respectively. The final part of this thesis focusses on the temporal evolution of topography in South East Tibet. Recently published paleoaltimetry results based on stable-isotope geochemistry are used to provide constraints on vertical motions. These demonstrate that uplift is much slower than had previously been suggested from thermochronometric data. Numerical modelling of the time evolution of a gravitationally-driven fluid is used to investigate the effect of lateral rheological contrasts on the shape and evolution of topography. In such a flow, material at the surface can be transported hundreds of kilometres, an effect which should be accounted for in paleoaltimetric analysis. Lateral rheological contrasts, analogous to the relatively undeforming Sichuan Basin and Central Lowlands of Myanmar, can reproduce the main features of the present-day topography, GPS velocity field and earthquake-derived strain rate without the need for a low-viscosity lower-crustal channel.
