TECTONIC SETTINGS AND METALLOGENISM OF THE EASTERN SEGMENT OF THE QIN-HANG BELT, SOUTH CHINA

The Qin-Hang Belt, an important metallogenic belt in South China, is situated in the junction of the Yangtze Block and the Cathaysia Block, bounded by the Jingdezhen-Xiangtan-Pingxiang Deep Fault Zone to the northwest of the Yangtze block and the Shaoxing-Xiangping-Beihai Deep Fault Zone to the southeast of Cathaysia Block.It has experienced the Jinning, Caledonian, Indosinian and Yanshanian movements successively, and suffered from oceanic subduction,continent-continent collision, formation of the South China Block, intensive intracontinental folding, Yanshanian reactivation, large-scale Mesozoic magmatism and formation of intracontinental basins.Various mineral deposits controlled by correspondent structural patterns were formed in the belt in different periods, especially the Yanshanian Period.
