摘要
Starting from to collect data,systematically analyze the Xie’ersu Basin coal accumulating environment and tectonic framework,Namely,Xie’ersu Basin in Late Jurassic-Early Cretaceous graben coal accumulating basin.Coal accumulation depends on the basin sedimentary environment and paleostructure environment,is lake swamp environment.Vertical sedimentary sequence is consistent with tectonic evolution stage of the basin,the subsidence axis and the sedimentary center showed NS distribution.
