查明早太古界麻粒岩杂岩的变质分带是一个迫切需待解决的问题。它的解决将有助于阐明这些杂岩的成因。但是,在经过多期变质改造而使最古老的分带消失了的地区,要研究这一问题是极其困难的。在阿尔丹-维季姆结晶地块南部占有广泛空间的斯塔诺夫褶皱区就属于这样的地区。根据已有的资料,在该地块麻粒岩中分布最广的,是中等变质的石 To identify the metamorphic granulite metamorphic zone is an urgent need to be resolved. Its solution will help clarify the causes of these complexes. However, it is extremely difficult to study this issue in areas where the oldest zoning has disappeared after many periods of deterioration and transformation. The Stanov fold zone, which occupies ample space south of the Aldan-Vidim crystalline massif, belongs to this area. According to the available data, the most widely distributed granulite in the block is the moderate metamorphic stone
