Based on highly detailed field investigations and test data from research on 98 different remnant basins, tectonic settings and lithostratigraphic sequences, this book describes the 4-stage evolution of the tectonic lithofacies paleogeography of the Qinghai-Tibetan Plateau, including Paleocene-Eocene, Oligocene, Miocene and Pliocene. It also discusses the contact relationship between the strata, the tectonic-lithofacies paleogeography evolution in the Cenozoic and their response to the tectonic uplift of the plateau. The continuous uplift and intensive intra-continental deformation during each turning point in the plateau divided the originally large sedimentary basins into numerous smaller ones filled with shrank of lacustrine-facies deposition and increased boulderstone accumulation, which indicates a response to the overall uplift of the plateau. Five major uplift events, which happened in 58-53 Ma, 45-30 Ma, 25-20 Ma, 13-7 Ma and since 5 Ma, respectively were identified. The paleogeographic configurations of the Tibetan Plateau turned over during the late Miocene, with high contours in the east during the pre-Miocene switching to the west after the Late Miocene

"The uplift history of the Tibetan Plateau serves as key evidence for understanding the dynamic models that build the Plateau and its influence on Cenozoic climate change of East Asia. This dissertation contributes to our knowledge for the growth history of the central and northern Tibetan Plateau through sedimentary analysis of basin sequences, and stable isotope analysis of carbonate rocks and modern surface waters. Field work in the Hoh Xil basin of central Tibet, including facies analysis, paleocurrent reconstruction, detrital zircon provenance analysis, and stable isotope analysis, suggests that a unified Hoh Xil basin, including both the east and west sub-basins, experienced a transition from pre-India-Asia collision foreland basin to post-collision hinterland basin setting at around 50 Ma. The Qiangtang terrane, serving as the main source for sediments deposited in the Hoh Xil basin, experienced significant topographic growth during the Cretaceous time. Far field deformation in the Hoh Xil basin was initiated shortly after India-Asia collision; contractional deformation and concomitant filling of the Hoh Xil hinterland basin provides clues for outward and upward growth of the Tibetan Plateau during Cenozoic time. Work in the western Qaidam basin provides new lithostratigraphy and carbonate stable isotope data that records early-middle Miocene topographic growth of the northern Tibetan Plateau. A hydrological change from restricted sub-basin to open marginal basin around 20 Ma was probably caused by late Oligocene-early Miocene tectonic activity around the Qaidam basinches A major topographic growth in the northern Tibetan Plateau is inferred around 15 Ma based on a negative shift in oxygen isotopic values, sedimentary facies changes from marginal lacustrine to fluvial, and an increase in sedimentation rate. A 13-12 Ma aridification event that was observed over a large area of the northern Plateau was likely caused by continued topographic growth to a critical point to block moisture from entering the northern Tibetan Plateau. To understand the caveats of stable isotope-based paleoaltimetry in the central and northern Tibetan Plateau, a comprehensive data set of 1,315 river water samples (450 newly collected) was compiled. With this large data set, a consistently assumed, but not well-documented prerequisite is demonstrated that river waters are a good substitute for isotopic studies of precipitation on the high Tibetan Plateau on the mean annual scale. The spatial variations of [delta]18O/[delta]D and d-excess values in the plateau margins can be modeled as a Rayleigh distillation process, on which stable isotope-based paleoaltimetry is based. On the contrary, the isotopic values of meteoric waters in the interior of the plateau are controlled by the combined effects of mixing of different moisture sources, contribution of recycled moisture from local surface water evaporation, and sub-cloud evaporation. A Rayleigh distillation model modified by sub-cloud evaporation is provided to simulate the isotopic variations in the western Plateau. This new understanding indicates that stable isotope-based paleoaltimetry is most reliable in the southern margins of the Plateau, and increasingly unreliable toward the northern Plateau. In addition, the contour maps of modern isotopic variations of meteoric waters across the whole Tibetan Plateau also provide validation criteria for isotopic simulations using general circulation models"--Pages v-vi.

Seismic Geology and Basin Analysis: Case Studies on Sedimentary Basins in China introduces the principles, approaches and techniques needed to solve problems using seismic data calibrated with well log, cores and outcrop profiles. The book emphasizes the adoption of seismic techniques into basin analysis and broadens the usage of seismic data in geological research which may be referred to as “seismic geology. The principle of the book is mainly summarized from a series of case studies in different basins in China. In addition, through this book readers can understand the primary characteristics and basin fill evolution of major petroleum basins around the world. When starting research on a basin, researchers and professionals are confronted with how to reveal the general architecture of basin fills and depict three-dimensional geometry, and the internal architecture of subsurface depositional bodies and their arrangement, hence this book is a great tome on necessary areas of exploration. Examines the adoption of seismic techniques into basin analysis and broadens the usage of seismic data in geological research Includes seismic, well log, core and outcrop data, as well as high resolution 3D seismic profiles and slices Features case studies to further illustrate principles and approaches described in the book, which can be applied to similar basins around the world

"This volume includes a variety of papers on the tectonics of the Tibetan Plateau and the Iranian Plateau that were presented at the first joint meeting between the Geological Society of America and the Chinese Academy of Sciences. Each paper deals with a different aspect of the geology and/or the geophysics of the tectonic evolution of the plateau. Although most of the papers discuss areas in the northeastern part of the plateau, one concentrates on the complexity of the Cenozoic shear zones in Yunnan and one focuses on the late Cenozoic extensional tectonism along the western margin of the Iranian Plateau. Several papers discuss aspects of Tibetan tectonics not covered in any other papers and arrive at unique interpretations."--Publisher's website.
