摘要
By stratum section mapping and sequence analyses of early Triassic in Xiuwen of Guizhou and Tiane of Guangxi,its facies are determined and zoned.According to lithology assemblage,biography assemblage,top and bottom boundary,it’s compared and studied,then the facies are zoned.It can be known that the sedimentary environment evolution of continental shelf in early Triassic in the target area is carbonate gentle slope sedimentary environment,translates to edging carbonate platform sedimentary environment finally,but Bangeng area in Luodian is isolated platform sedimentary environment.Meanwhile,two 3-level sequences of early Triassic are set up in the target area.
