| 摘 要： | 滇西瑞丽地区的中下三叠统可划分为三角洲（泻湖）、碳酸盐台地两种相区。三角洲（泻湖）相区下三叠统为扎多组（T1z）；中三叠统为伙马组（T2hm）：碳酸盐台地相区中下三叠统河湾街组（T1-2h）。对扎多组、伙马组重新划分，进行沉积环境分析，确定扎多组、伙马组与河湾街组之间是相变关系，为研究古代三角洲与障壁海（泻湖）及局限台地的沉积环境、相变关系提供了良好实例。

| Abstract: | The Middle - Lower Triassic in Ruili area of West Yunnan can be divided into 2 facies, ie delta （lagoon） and carbonate platform. The Lower Triassic in the delta （lagoon） facies area is Zaduo Formation （T1z） , the Middle Triassic is Huoma Formation （T2hm） . The Middle -Lower Triassic in carbonate platform facies area is Hewanjie Formation （T1 _2h） ~ According the re -division of Zaduo Formation and Huoma Formation and the anal- ysis of sedimentary environment, we determine the facies change of Zaduo Formation, Huoma Formation and He- wanjie Formation, which can provide a good example for the study of sedimentary environment and facies change of old delta, barrier lagoon and limited platform. |
