本文从洋壳俯冲导致陆壳构造—岩浆活化的观点出发,将浙江列于俯冲—拱裂型地洼。浙江境内以萧山—常山断裂为界,其西侧属华中地洼区,其东侧属东南地洼区。进一步划分出4个二级构造单元,8个三级构造单元。笔者提出钱塘裂谷地洼系,它是出现于前晋宁期,萎缩于晋宁末期的古裂谷;它经过地台阶段以后,又于地洼阶段复活。 Based on the subduction of oceanic crust, which led to the continental crustal tectono-magmatic activation, Zhejiang is listed in depression of the subduction-arch fractures. Zhejiang Province to Xiaoshan - Changshan fault as the boundary, the west of Central China depression area, the east side of the southeast depression. Further divided into four secondary structural units, eight tertiary structural units. The authors propose that the Qiantang rift valley depression, it is appeared in the former Jinning period, shrinking in the late Jinning ancient rift; it after platform stage, and resurrection in the Diwa stage.
