| 摘 要： | 本文通过国内外绿岩带及其中的金矿床对比研究,说明我国早前寒武纪变质岩系的原岩层序和岩性特征与世界各绿岩带是可以对比的;我国早前寒武纪变质岩系中的金矿床在赋矿围岩、控矿构造及产出形式诸方面与绿岩型金矿也是可以对比的。从其成矿机理及基本事实出发,指出在我国早前寒武纪变质岩分布区及已知老矿区寻找深部矿体的可能性。

| Abstract: | The comparision of gold deposits in between greenstone belt abroad and Early preca-mbrian metamorphic rocks of China shows that the succession of strata, lithological characters of metamorphic rocks of Early Precambrian in China are comparable with those of greemstone belt abroad. The country rocks, ore controlling structures and occur-res of the gold deposits in the Early Pfecambrian metamorphic rocks are also similar to those in the greenstone belt abroad. It suggests the possibility of searching for deepseated gold deposits in areas of Early Precambrian metamorphic rocks and in old mines of China. |
