前寒武纪金矿床的成矿作用:空间和时间的关系 Metallogeny of precambrian gold deposits: spaca and time relationships, R.W. Hutchinson 前寒武纪岩层中金矿床的广泛成矿关系提供其成因的一些标志,虽然常常被忽视,但在勘查工作中是有用的。仅有两种重要的金矿类型,即产于绿岩的金矿脉和古砂矿。许多重要金矿脉都产在各太古宙克拉通的主要绿岩带中,并与太古宙其他重要矿床 Metallogeny of precambrian gold deposits: spaca and time relationships, RW Hutchinson The extensive mineralization of gold deposits in the Precambrian strata provides some of the causal evidence for their genesis, though often Neglected, but useful in prospecting. There are only two important gold types, gold veins and paleosites originating in Greenstone. Many important gold veins are produced in the major greenstone belts of various Archean cratons and associated with other important deposits of the Archean
