| 摘 要： | 从岩性，化石，生物地层，沉积环境等方面对元江地区三叠系地层特征进行讨论。通过与邻区对比，元江地区的上三叠统应划属滇东南地层区，与火把冲组相比。根据所获化石建立Burmesia-Costtoria-Indosinion组合带，归属诺利－瑞替阶，对研究云南三叠纪地史，恢复古地理，古地貌具有重要意义。

| Abstract: | The lithological characters, fossils, biostratigraphy and sedimentary environment of Triassic in Yuanjiang area are discussed in this paper. According to the correlation with nearby areas, the Upper Triassic in Yuanjiang must be divided into the Southeast Yunnan stratigraphic region, correlated to Huobachong Formation. And the Burmesia-Costtoria-Indosinion zone has been set up according to the obtained fossils, which can be correlated to Noric-Rhaetic. These results are significant in the study on historical geology, palaeogeography and palaeogeomorphology of Triassic in Yunnan. |
