新疆昆仑山西北缘早石炭世早期地层称库山河组,该组分布面积不大,主要见于昆仑山西北缘阿克陶县库山河地区,1981年新疆地矿局第二地质大队综合组首次发现并测制剖面,1984年新疆地矿局第一区调大队五分队再次详细测制剖面,系统采集化石,其层序更为清楚,是新疆南部地区早石炭世地层一个比较理想的层型剖面。本文描述的皱纹珊瑚主要是区调五分队所采。
The early strata of Early Carboniferous strata in the northwestern Kunlun Mountains of Xinjiang called the Ku Shan Shan Formation, which is not large in area and mainly found in the Ku Shan River area of Ake Tao County in the northwestern edge of the Kunlun Mountains. In 1981, for the first time, the Comprehensive Geological Brigade of Xinjiang Bureau of Geology and Mineral Resources And measured the profile. In 1984, the fifth detachment of Xinjiang Uygur Autonomous Region and Region Militar Detachment 5 detachment made a detailed survey of sections and systematically collected fossils. The sequence of the fossils is more clear and it is an ideal stratigraphic section of the Early Carboniferous strata in the southern part of Xinjiang. . The wrinkled corals described in this paper are mainly collected by the ex-wards.
