中国绿岩带型金矿床类型和地质特征

绿岩带型金矿床是世界和我国重要的金矿床类型。中国绿岩带型金矿床可分为同构造晚期初生型金矿床和构造期后再生型金矿床二类。这二类金矿床的成矿地质环境、矿床地质地球化学均具有明显的不同。同构造晚期初生型金矿床不仅产出在中低变质绿岩带中，而且在高级变质绿岩带中分布很普遍和发育。构造期后再生型热液金矿床分布广泛、储量极大，是具有中国地质特色的金矿床类型。

TYPE AND GEOLOGICAL CHINESE GREENSTONE BELTS GOLD DEPOSITS

Greenstone belt gold deposits are most important type of gold deposits in worldand China. The chinese greenstone belt gold deposits can be divided into two types. One type islate syntectonic primary gold deposits, the other type is post-tectonic regenerated gold deposits.It is evident difference of metallogenic geological environment and geological chemistry betweentwo types. The late syntectonic primary gold deposits not only are distribution in the low-middlegrade metamorphic greenstone belts, but also are widely spreaded in the high grade metamorphicgreenstone belts. The post-tectonic regenerated hydrothermal gold deposits are wide spreadlydeveloped, vast reserves and type of gold deposits of chinese particular feature.
