On Dynamics of the Metallogenic Belt of Middle-Lower Reaches of Yangtze River, Eastern China
详细信息   
摘要

///The Middle-Lower Reaches of Yangtze River is a well-known Mesozoic metallogenic belt in central East China. In view of geological evolution and metallogenic dynamics, the Middle-Lower Yangtze metallogenic belt has its own distinguishing features in China, even in the world. Firstly, the tectonic background and processes had experienced the environments from plate margin to intra-plate during T2-J2, and mineralization occurred in transformation from compression to extension (145~130 Ma). Secondly, diagenesis and mineralization in the belt were controlled by base structure and deep process, and related to its own basement. In conclusion, the Middle-Lower Yangtze mineralization had occurred through the whole Yanshanian epoch (165120 Ma) and distinctly recorded the imprint of subduction of Pacific Plate during Late Jurassic to Early Cretaceous.
