摘要: 东昆仑西段布喀达坂峰地区发现了以单通道(Monodiexodina)为主的冷温动物群,产于东昆中缝合带与东昆南缝合带之间一套以浅海相碳酸盐岩为主的中下二叠统中,可与空喀山口加温达坂组及西藏吞龙共巴组对比

Abstract: The authors discovered a cold-water fau na dominated by Monodiexodina in the Mount Buka Daban area,western segment of the East Kunlun Mountains.It occurs between the central suture zone and south suture zone of East Kunlun.The fossils occur in Early-Mid Permian strata consisting dominantly of neritic carbonate rocks.The strata can be correlated with the Jiawen Daban Formation in the Kongka Pass,Xinjiang,and the Toinlunggongba Formation,Tibet.
