摘要
在兴义乌沙地区出露广泛的上三叠统法郎组瓦窑段地层,通过对其沉积环境特征进行分析,共识别出4种标准微相类型。根据微相分析并结合岩相古地理及层序地层推断其沉积环境为淹没台地。
Abundant Wayao section layer of Falang formation,upper Triassic emerge in Wusha area of Xingyi,by analyses its sedimentary environmental features,4 standard micro-facies type are identified.According to microfacies analysis,lithofacies paleogeography and sequence stratum,it＇s inferred that the sedimentary environment is carbonate platform.
