摘要
华北陆块北缘中段是我国地壳发展和演化历史最久的地区之一 ,它是我国最古老的华北古大陆的一部分 ,也是重要的矿产资源基地之一。从太古宙古陆块的形成至元古宙原始地壳的增生发展 ,直到中新生代构造岩浆强烈活化改造 ,本区经历了复杂多变的不少于 8次重大的地质事件和演化阶段 ,与此同时形成了大量的铁、金、铅、锌、钼、银、铜、锰等矿产。
The middle north margin of North China craton is one of the area where the history of the earth's crust develop and evolvement is for a long time. It is important portion of the old North China craton. It is also the one of the area where becoming the important basement of mineral resources in China. In this region, from the old Archean old craton block occurred, and the Proterozoic originality crust accretion and development, to strongly tectonomagmatic activation and alteration in Mesozoic and Cenozoic, the crust formation underwent at least 8 phases of the geological event and evolvement. In the meantime, large numbers of iron, gold, zinc, molybdenum, silver, copper, manganese, etc. ores had been formed.
