In qinghai province , it reveals that the au deposits are mostly distributed on the sits between different tectonic units ; and in the edge of the exposed and / or concealed metamorphic basement of the early sinian period ; in the area of the exposed and concealed acid - instrusions and / or their contacts ; and in the localities where the circular and linear anomalies of graviation and magnetism cut across 结果表明，该区的金矿大都分布在不同大地构造单元结合部位；处于前震旦纪变质岩系出露及隐伏基底边缘；位于出露和隐伏中酸性岩体及其接触带；位于重磁环线、线线构造交汇处等。
Multistage structural deformations are experienced in kongquehe area , the basical fault systems of nww - near ew , nne - near sn , nnw and nee are established , the fault movement has the characteristics of multistage and inheritance , in the area multi - structural deformations are experienced in sinian to early ordovician , early ordovician - silurian , jurassic cretaceous - caenozoic , etc . late structural deformation shapes are changed for different levels of formar structural layer , in which different deforming shapes are created and integrated overlying of deformation is induced 摘要孔雀河地区经历了多期次的构造变形作用，形成了现今北西西近东西向、北北东近南北向、北北西向和北东东向基本断裂体系，同时断裂活动表现为多期性和继承性的特点；该区经历了震旦纪至早奥陶世、早奥陶世末志留纪、侏罗系、白垩纪新生代等多期构造变形作用，且后期的构造变形作用在不同程度上对前期的构造层的变形样式有所改造，形成了有一定差异的变形面貌，造成变形的复合登加。
Some conclusions are listed as follows : the plateform cover cap of ordos basin and its circumference areas can be divided into five tectonic sequences . the tectonic evolution of ordos basin can be classified in six stages : the basement formation phase ( from archeozoic to paleoproterozoic ) ; the aulacogen phase ( from mesoproterozoic to neoproterozoic ) ; the north china continental sea phase ( from sinian to early - paleozoic ) ; the north china intracratonic depression phase ( from late - paleozoic to early mesozoic ) ; large ordos inland basin phase and the formation of independent ordos basin ( mid - late mesozoic ) ; fault basin phase around the ordos basin ( cenozoic ) 通过研究有以下成果及认识：鄂尔多斯盆地及其周缘地区沉积盖层可划分为五大构造层序，盆地的形成和演化分为六大构造阶段：太古代至古元古代基底形成阶段、中新元古代克拉通内裂陷槽或坳拉槽演化阶段、震旦纪?早古生代华北陆表海盆演化阶段、晚古生代?早中生代华北克拉通坳陷演化阶段、中生代中晚期大鄂尔多斯内陆盆地演化阶段及独立鄂尔多斯盆地的形成、新生代周缘断陷盆地演化阶段。
In a study on a sedimentary basin analysis of the huanan orogenic belt , the sedimentary basin character and evolution in the southeastern passive continental margin of the yangtze plate is investigated with elaborate sedimentary environments and sedimentary character from the sinian to the triassic , and then the sedimentation sketch of this belt is established especially to be from rift , passive continental margin into foreland basin in the early paleozoic on the yangtze plate 在华南造山带沉积盆地分析和演化研究中，对扬子大陆东南边缘从震旦纪到三叠纪沉积环境，沉积作用特点，沉积盆地性质和演化进行研究，特别是建立了中国南方扬子板块早古生代从裂谷，被动大陆边缘到前陆盆地华南造山带沉积作用格架。
