为闸明太古宙绿岩带成因的机械作用有几种提法,每一种观点都争论很热烈。最早的模式把绿岩带的地层顺序与海洋壳的剖面视为一致,认为周围的花岗片麻岩有更年轻的年龄,但是在此带的古老沉积岩中找到了成分与现代沉积相似的硬砂岩,这说明了古老大陆硅铝质岩体经过剥蚀,这种现象在阿尔丹及加拿大地盾,南非及澳大利亚见到。后来的模式与第一种不同,他们认为绿岩带与断裂的成因及硅铝壳的拉开有关。按这种提法,在绿岩带底部应有橄榄岩分布,但实际任何地方也未找到。
There are several formulations for explaining the mechanical role of the Archean greenstone belt, each of which has a very heated debate. The earliest model agreed with the sequence of the stratigraphic sequence of the greenstone belt and the profile of the marine shell, suggesting that the surrounding granitic gneiss has a younger age, but in the ancient sedimentary rocks of this belt there was found something similar to modern deposits Sandstone, which illustrates the erosion of ancient continental sillimanite bodies, is seen in the Ardien and Canadian Shields, South Africa and Australia. Later models differed from the first one in that they considered the greenstone belt to be related to the genesis of the fault and the opening of the Si-Al shell. According to this formulation, there should be peridotite distribution at the bottom of the greenstone belt, but it has not been found anywhere else.
