| 中文摘要:Geologic studies of the Late Creta-ceous Paleogene stratigraphic record of southern Tibet reveal distinct episodes of collision and post collisional compression. The composition of sediments exposed along the Indus-Yarlung Zangbo suture, tectonic deformation, paleomagnetism, mag-matic activity of the Gangdese Arc, high pressure metamorphism, paleobiogeography and terrestrial bi-ota changes have been variously used to diagnose the timing of Indian-Eurasian continental plates collision. Among them, paleobiogeography and marine facies cessation are visible scenarios to trace the continental collision. This study recognized that dramatic changes of paleobiogeography happened during early Paleo-gene. |
