摘要
矿区经历了地槽-地台-地洼三个构造发展阶段;矿区的一组北西西向断裂是多次活动的切壳深断裂,是矿区的主要导岩导矿构造,而北东~北东东向构造仅是容矿构造,其类型主要有四种;矿区的近外围找矿应重点沿北西西向导岩导矿构造展开。
Baoshan area has passed three geotectonic stages which are geosyncline-platform-geodepression. A series of faults trending NWW In the area are deep-seated faults with manytimes of activity, and are primary structures through which magma and mineralization materials passed. NE-NEE structures are only host structures which are of four kinds of types.The prospecting area should be studied along NWW structural belts.
