Yangzi Faulting-block region is confined by lithospheric faults on its boundaries with distinct structural characters and geophysical anomalies. Differences in cover rock structural style is to some extent a manifestation of heterogeneity of the basement of this area. The Basement of Yangzi faulting-block region is heterogeneous and can be divided into Yangzi miogeosyncline and Jiang-nan eugeosyncline, showing downstep faulting from north to south, west to east. The heterogeneity of the basement is controlled by lithospheric faults and crust faults and differential movement of faulting blocks. These faults probably formed early in the middle proterozoic ear and controlled or affected the evolution of Yangzi faulting-block region and its vicinities, the structural styles and their development within the faulting block. The. trans formation of Jinn-ing geosyncline into a unified basement of Yangzi faulting block was through polyphase extension and compression.
