摘要
贵州省位于我国西南地区,扬子陆块西南缘与华南褶皱带"焊接"形成的大陆地壳。在"东亚旋涡"(假说)作用下,导致多期次构造运动,产生以NW向的紫云—垭都深断裂为界,北东部以SN—NNE—NE向为主的构造;而南西部以NW向和旋扭为主的构造,提供了极为有利成矿条件,成为贵州重要矿产资源集中区,由此研究贵州省大地构造和指导找矿具重要意义。该"假说"也是全球板块运动和碰撞的动力来源,对研究全球大地构造、成矿预测及地震预报也具重要意义。
Guizhou province is located in southwest China,a continental crust formed by "welding"with the southwest edge of Yangzi continental block and the south China fold belt .Effected by "east Asian vortexes (hypothesis)",multiple tectonic movements are generated,which is bounded by the deep Ziyun-Yadu fault in the direction of NW and dominated by the SN-NNE-NE structure in the east of north,and the structure of the south west is dominated by NW and twist,and provides a highly favorable conditions of mineralization,making it an important mineral resources concentration area in Guizhou.Theerefore,it has great significance to study geotectonics and guide ore prospecting in Guizhou province.The "hypothesis"is also a dynamic source of global plate movement and collision,and it is also of great significance to the study of global tectonics,metallogenic prediction and earthquake prediction.
