中国新近纪构造-地层区划及地层格架

新近纪是中国地貌地形和气候环境格局最终奠定的关键时期,如青藏高原强烈抬升和现代高原地貌最终成型、中国南海海盆扩张结束、东亚现今大型水系格局最终建立、中国西高东低的地势最终确立以及东亚季风系统开始形成并逐渐增强.通过对中国新近纪大地构造、沉积盆地(群)、火山岩、隆起带和大型变形构造等的综合研究,共厘定一级构造-地层单元(...

Neogene Tectonic-Stratigraphic Realms and Sedimentary Sequence in China

Neogene is the key period for the establishment of geomorphology and pattern of climate changes in China, involving the significant uplift of Tibetan Plateau and final formation of modern plateau landform, the termination of seafloor spreading for the South China Sea, the final establishment of the present large river system in East Asia, the final establishment of the west-tilting topography of China, the formation and enhancement of East Asian monsoon system. Through the comprehensive study of Neogene tectonics, sedimentary basins (groups), volcanic rocks, uplifting belts and large deformation structures in China, 10 first-order tectonic-stratigraphic units (super-realms) and 27 second-order tectonic-stratigraphic units (realms) have been subdivided, including 94 basins. Through the research of the types of basins in each unit, sedimentary sequence, sedimentary age and stratigraphic contact, the Neogene lithostratigraphic correlation framework in China was established and the sedimentary-tectonic-climate history was summarized.
