The main continent rift developed in mid - late proterozoic ; the paleo - asian tectonic dynamic system played an important role in the paleozoic period ; the combination of tethys - paleopacific tectonic dynamic system influenced the basin in mesozoic . during that period , the tethyan dynamic system affected the basin in the early stage ( t ) while paleo - pacific dynamic system affected it in the latter stage ( js - k ) ; the new tethyan - circum pacific tectonic dynamic system dominated in cenozoic period 中新元古代为大陆裂谷集中发育阶段；古生代主要受控于古亚洲构造动力学体系；中生代主要受控于中特提斯?古太平洋构造动力体系的联合作用和影响，其中早期( t )主要受特提斯动力体系影响，晚期( j _ 3 - k )主要受古太平洋动力体系影响；新生代主要受控于新特提斯?今太平洋构造动力体系的联合作用和影响。
The research for metallogenic evolution mechanism in the region indicates that gold ore formation has undergone three stages : gold elementary source bed formation stage from the neo - archean to the paleo - proterozoic and meso - proterozoic , regional metamorphism - migmatization gold reenrichment stage at the late meso - proterozoic , structure - fluid - gold mineralization stage at the yanshan period 对矿带成矿演化机理的研究表明，金矿形成经历了3个阶段：新太古至古、中元古代金初始矿源层形成阶段；中元古代末期区域变质混合岩化金再富集阶段和燕山期构造流体金成矿作用阶段。

The mesoproterozoic mafic dyke swarms are extensively distributed in the central north china craton , which are not deformed and metamorphic , emplacing the pre - existed fractures , so the dyke swarms become the conspicuous marks to reconstruct the mesoproterozoic tectonic stress field of the central ncc . the mafic dykes in the northern block are transtensional while the dykes in the central and southern blocks are extensional . the mesoproterozoic tectonic stress field could be simulated on the analysis of the distribution and mechanical origin of the mesoproterozoic mafic dyke swarms in the central ncc . the simulation result shows that the mafic dyke swarms were formed in the extensional tectonic setting in the ncc in the mesoproterozoic time , which are related to the extension of the mesoproterozoic yanliao - zhongtiao aulacogens cross the central ncc 克拉通北部地块的镁铁质岩墙群为张剪性，而中部和南部地块为张性。根据华北克拉通中部中元古代镁铁质岩墙群的分布和成因机制分析，来恢复模拟中元古代的构造应力场。数值模拟结果表明镁铁质岩墙群在中元古代形成于伸展的大地构造背景，与横穿华北克拉通中部的燕辽-中条拗拉槽系的伸展作用有一定的联系。
