摘要
The quantitative sedimentary facies and palaeogeographic map of the middle-upper Yangtze area during the Leikoupoan (Middle Triassic) is constructed on the basis of single factor and multiple factors mapping methods. The resulted in the gradation of the study area into the shallow-water depositional area, and no basin and slope were developed. The Leikoupoan (Middle Triassic) palaeogeographic evolution and sedimentary model are presented in this study for the study area.
