目前,许多研究者通过对变质黑色片岩层中金矿床的研究得出了这样的结论,即金矿床是由原始沉积岩变质而成的。这一点已为下述事实所证实:这些黑色片岩中的金矿床主要产于变质程度达绿片岩相(据А.А.Маракушев资料,从泥质片岩相到云母片岩相)的变泥岩
At present, many researchers have concluded from the study of gold deposits in the metamorphic black schist formation that the gold deposits were altered from the original sedimentary rocks. This is evidenced by the fact that the gold deposits in these black schists are predominantly of metamorphosed mudstones of metamorphic facies (from the argillaceous to the mica schist) according to the data from А.А.Маракушев
