The Middle-Lower Triassic in Ruili area of western oft-com:office:smarttags" />Yunnan Province can be divided into 2 facies, i.e., delta (lagoon) and carbonate platform.  The Lower Triassic in the delta (lagoon) facies area is Zaduo Formation, the Middle Triassic is Huoma Formation.  The Middle-Lower Triassic in carbonate platform facies area is Hewanjie Formation.  According the re-division of Zaduo Formation and Huoma Formation and the analysis of sedimentary environment, the authors determine the facies change of Zaduo Formation, Huoma Formation and Hewanjie Formation, which can provide a good example for the study of sedimentary environment and facies change of old delta, barrier lagoon and limited platform.  oft-com:office:office" />
