| Abstract: | Xiangqian-Jiangnan paleo-fault zone traversing the southeastern continent of China is the fault zone that made the protoplatform split during early Proterzoic.' This fault zone corresponding to Jiangshan-Shaoxing paleo-fault zone was the lithospheric fracture since it controlled the forming of "Dongnan primary eugeosynclinal system" during the period of strong activity of mid-Proterozoic (1700-900 Ma.). Until Sinian-Silurian (900-400 Ma), the activity of the fault zone weakened gradually, and the fault zone probably belonged to the crustal fracture which differs Yangtze paraplatform from the Dongnan Caledonian geosynclinal system. The difference in structure-lithofacies zone, magmatic evolution of Mesozoic and the character of mineral-bearing were all controlled by the difference in the basement structure of the platform and geosyncline, as well as influence of the movement of the fault zone.From above-mentioned it is obvious that Xiangqian-Jiangnan paleo-fault zone was both the important boundary between the platform and geosyncline system, and the rock- and mineral-controlling tectonic belt. |
