华北板内深部构造与区域成矿

本文应用深部地球物理资料，认为华北板块的形成经历了早前寒武纪、燕山期及喜马拉雅期。由于华北板块自身及周围板块的相对运动，上地幔岩石圈的不均一性等特点，造成了许多板内构造单元，如阴山板缘带、鄂尔多斯稳定硬块，河－淮活动软块、燕山活动硬块、山西过渡地块、鲁皖相对硬块及秦岭板缘带。笔者还划出了６个金及多金属成矿带，郯庐金刚石成矿带及华北西部金刚石远景带。此外，华北地区的地热田皆为新生代大陆裂谷型，计有河淮大型裂隙地热带及汾渭线状裂谷地热带。

DEEP-SEATED STRUCTURES OF NORTH CHINA INTRAPLATE AND THEIR BEARING UPON REGIONAL MINERALIZATION

Basing on the deep geophysical data and the characteristics of the deep-seated structureof North China,the authors consider that the generation of North China Plate had undergoneearly Precambrian stage,Yanshan stage and Himalaya stage,In the meantime,owing to thefeatures of the relative motion of North China Plate and other plates around it,the inter-transformation of lithosphere-asthenosphere of the upper mantle and the inhomogeneity oflithosphere,many intraplate tectonic units are formed,such as Yinshan plate edge zone,Or-dos stable solid mass,He-huai active soft mass,Yanshan active solid mass,Shanxi transition-al mass,Lu-wan relative solid mass,and Qinling plate edge zone.The authors also determinedsix gold and multimetal mineralization belts,i.e.Tanlu diamond mineralization belt and dia-mond prospective belt of western North China.In addition,the types of geothermal field ofNorth China are recognized as continental rift type of Cenozoic era,they are He-huai largefracture geothermal belt and Fenwei linear rift geothermal belt.
