摘要
In this paper, the Middle-Lower Yangtze River area is divided into the five tectonic units:the North China Block, the Dabie Orogenic Belt, the Yangtze Block, the Cathaysia Block, the Middle-Lower Yangtze River Foreland Belt. Furthermore, the Middle-Lower Yangtze River Foreland Belt is subdividied into three subunits:the Baokang-Wuhan-Susong-Chaohu Fold-and-thrust Belt,the Daye-Huaining-Wuhu Mesozoic Depression,the Tongshan-Ruichang-Ningguo Fold-and-thrust Belt.In the Middle-Lower Yangtze River,the south-directed thrusting should be related to the slow extrusion of the UHP metamorphic rocks in the Dabie Orogenic Belt.However,the northwest-directed thrusting may be related with the Middle Jurassic subduction of the Paleo-Pacific Plate to the Asian Continent.
