世界上特别是加拿大的许多重要的太古宙金矿床，都是产在绿岩带内或其附近的岩石中。这些岩石的变质程度从次绿片岩相到角闪岩相。从这些矿床的研究获得的重要成因模式，可以解释这些矿床所具有的特征。有些专有模式是属含金流体成因的变质脱氧模式，有些是与长奖质侵入岩有成?
Many of the major Archean gold deposits in the world, and particularly in Canada, are found in rocks within or near the Greenstone Belt. These metamorphic rocks range from sub-greenschist facies to amphibolite facies. The important patterns of genesis obtained from the studies of these deposits explain the characteristics of these deposits. Some proprietary models are metamorphosed deoxygenation modes that are responsible for the formation of gold-bearing fluids, and some are successful with long-range intrusive rocks?
