| 摘 要： | 厂坝-李家沟铅锌矿床是典型的海底热水沉积(SEDEX型)矿床。矿床地质特征、矿区地层的地球化学特征、以及同位素地球化学特征和区内古地热异常与热事件等的综合分析,表明厂坝-李家沟铅锌矿床的成矿金属元素主要来源于元古界碧口群和志留系白龙江群;多期(包括加里东+海西+印支)构造运动和幅度较大的裂陷发育史,为大量矿质的喷流和聚集提供了十分有利的导矿和容矿构造条件;花岗岩类及其他岩类的岩浆活动,不仅导致了地热异常的产生,为含矿热液对流体系形成与运行提供了巨大热源,同时还为区内成矿作用提供了部分矿源和水源。

| Abstract: | The Changba-Lijiagou lead-zinc deposit belongs to the SEDEX type deposit. All the studies on its geological,regional stratigraphic geochemical and istopic geochemical characteristics and geothermal anomaly,showed that the minerogenetic matter of the Changba-Lijiagou lead-zinc deposit came mainly from the Proterozoic Bikou Group and Silurian Bailongjiang system. A few tectonic movements(such as Caledonian,Hercynian,Indian) and the rifting with big range lift-fall made a great quantity minerogenetic matter to... |
