最近十年中,对于占世界黄金产量一半以上的太古代金矿床的许多直接和间接的(威特沃特斯兰)研究认为,太古代镁铁质—超铁镁质岩是该时期金矿床的矿源岩(Boyle,1961等)。事实上,太古代一些地区的金矿化与沿着断层带显示的碳酸盐—硫化物蚀变的镁绿岩有密切关系(Hutchison 等1894),说明镁绿岩是金的初始源岩。对于各种蛇绿岩杂岩中的超铁镁岩体的类似的金矿化和蚀变矿物学特征也已有所了解(Buisson等,1986)。这种金矿化发生于各种蛇绿岩组合的碳酸
In the last decade, many direct and indirect (Witwatersrand) studies of Archean gold deposits, accounting for more than half of the world’s gold production, suggest that the Archean mafic-ultramafic rocks were Source rock (Boyle, 1961, etc.). In fact, gold mineralization in some areas of the Archean was closely related to the carbonate-sulfide altered magmatic rocks along fault zones (Hutchison et al., 1894), suggesting that mafic rocks are the primary gold source rocks. Similar gold mineralization and altered mineralogical characteristics of the ultradine magmatic rocks in various ophiolite complexes are also known (Buisson et al., 1986). This gold mineralization occurs in various combinations of ophiolite carbonates
