武当山块北缘晚震旦世—早古生代沉积盆地的构造沉降分析

Tectonic subsidence of sedimentary basin of late Sinian to early Palaeozoic in northern margin of Wudang mountslab

运用盆地分析方法，着重研究了武当山块北缘晚震旦世—早古生代沉积盆地的构造沉降问题．构造沉降分析表明：晚震旦世属盆地同裂谷期沉降阶段；早、中寒武世为被动式衰减热沉降阶段；晚寒武世—中奥陶世为构造上升阶段．

By means of the basin analysis, this paper has emphatically studied the tectonic subsidence of the sedimentary basin from the late sinian to the early paleozoic in the northern margin of the Wudang mount slab. The tectonic Subsidence analysis demonstrates that the basin can be divided into the basin′s Syn rift stage of the late sinian, the basin′s passive decline thermal Subsidence stage of the early middle Cambrian and the basin′s tectonic rising stage from the late Cambrian to the middle ordovician.
