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