【摘要】 华北陆台北缘分布的前寒武系是我国境内古老、复杂而且规模宏大的岩性构造带。这个岩性构造带记录了前寒武纪众多的地质信息，赋存着大量与之有关的多金属、贵金属及非金属矿产，同时还控制着中国北方前寒武纪以后的地质演化和成矿作用。因此，正确认识华北陆台北缘早期地壳演化，评价区内成矿作用和矿产分布规律，具有十分特殊的理论意义和重大经济效益。更多还原

【Abstract】 The Precambrian system distributed on the North Margin of North China Platform is anold,complex and large-scale lithologic-tectonic belt,which records a vast amount of geologi-cal data,contains metal,precious metal and nonmetallic ore deposits and controls the geologi-cal evolution and ore-forming process during post-precambrian in North China. For this rea-son,correctly understanding the early stage of the crust evolution,evaluating mineralizationand ore distribution in the area are of special theoretical significance and great economic ben-efit.更多还原
