作为古地台太古代绿岩带类似物的阿尔丹-斯塔诺夫领域内的晚太古-早元古代的冰川槽构造,引起很多研究者的注意。该构造在平面上组成彼此分隔开的、近南北向较少近东西向的狭窄线状带,大多数冰川槽,被主要是陆源-火山铁-硅质建造和较少的碳酸盐-陆源建造的沉积物所填满(图1)。这些沉积物,在晚太古-早元古代时期,遭受过多阶段的褶皱作用和角闪岩相(较少绿片岩相)的进化变质作用。于早元古代,构造还遭
Late Archean-Early Proterozoic glacial trough structures in the Ardan-Stonov field, which are analogues of the Paleogene greenstone belt in the Paleogene, have attracted the attention of many researchers. This structure is composed of flat, narrow-shaped bands spaced near each other in the north and south direction. Most of the glacial trenches are mainly composed of terrigenous-volcano-iron-siliceous structures with less carbonate- Land-built sediment filled (Figure 1). These sediments, in late-Archean-Early Proterozoic age, undergo excessive stages of folds and evolutionary metamorphism of amphibolite facies (less greenschist facies). In early Yuan Dynasty, the structure was also suffered
