The geochemical boundary between South China and Yangtze Blocks and its constraint oh the formation of super large deposits

ZHU Bingquan , CHANG Xiangyangand WANG Huifen(Institute of Geochemistry of Guangzhou, Chinese Academy of Sciences, Guangzhou 510640, China)  
It is indicated based on the isotope mapping in the South China that there existed an abrupt changing zone of Pb isotopes (ACZ) between the South China and Yangtze Blocks, which marks their boundary. This boundary controled the genesis of all of the super large deposits related with deep source mineralization, whose occurrence positions were tightly associated with contract and turning of ACZ along with forming contour line trap at both sides of the boundary. ACZ was usually consistent with the positive anomaly of gravity and approximately corresponding to the geological boundary currently recognized, but did not well match the major tectonic lines occurring on the surface.
