| 摘 要： | 西南天山哈拉奇地区康克林组第三段发现大量单体无鳞板四射珊瑚,经鉴定共有11属23种。根据该动物群的组成特征和与邻区的对比,建立了Amplexocaniaia-Tachylasma-Bradyphyllum组合,并确定其时代为早二叠世紫松期或阿舍尔(Asselian)期。通过对沉积相及该无鳞板四射珊瑚动物群古生态的对比分析,确定本区当时水深大于100m,属碳酸盐台地与盆地之间的过渡环境。

The discovery of Early Permian rugose coral Cyathaxonia faunas from Kangkelin Formation in Southwest Tianshan Mountains and its geological significance |

| Abstract: | Abundant small solitary corals without dissepiments were found in the strata of 3rd member of Kangkelin Formation within Karaqi area, and identification shows that these fossils include 11 genera with 23 species in total. On the basis of the characteristics of these corals and the stratigraphic distribution, the Amplexocaniaia-Tachylasma-Bradyphyllum assemblage can be established, belonging to the Early Permian Zisongian stage or Asselian stage. It is also suggested that the environment belonged to a carbonate platform-basin transition depositional environment, where the water was deeper than 100m. |
