摘　　要：华北板块的形成经历了早前寒武纪、燕山期及喜马拉雅期 3个主要构造发展期 ,由于华北板块自身运动及所受应力场的作用 ,加之上地幔岩石圈的不均一性等因素 ,在中、新生代形成许多特殊的板内构造块。综合应用地质、地球物理和地球化学的成果 ,对华北板内深部结构进行了研究。从深部构造角度划分出 6个金及多金属成矿带、4个金刚石成矿带 ,并对华北地区的地震及地热资源与新生带大陆裂谷的关系进行了探讨。main developing periods,which are early Precambrian periodin,Yenshan and Himalaya epochs come through in the formation of the North China plate.Many special tectonic blocks in the intraplate in Mesozoic and Neozoic era were formed,due to the movement of the North China plate itself,stress field acted on it as well as heterogeneity of the lithosphere of the upper mantle.a study on deep seated structure of the North China intraplate is made,by comprehensively using the results from geology,geophysics and geochemistry.Base on the deep seated tectonics,6 gold multi metal and 4 diamond mineral formation zones are mapped out.Also,some discussions on the relation between earthquakesas well as geothermal resource and the continental rift in the Neozoic era aremade.
