The Qin-Hang Belt is situated in the junction of the Yangtze Block and the 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.
