摘要
在新疆伊吾煤矿一带1:5万区域地质矿产调查中,首次在原定石炭系上统妖魔梁组中发现大量透镜状钙质结核,并具明显的陆相冲积扇沉积特征;通过该地层的大量孢粉鉴定属为二叠世晚期,故将原石炭系上统妖魔梁组更名改为库莱组。其时代定为晚二叠世。并初步探讨了它的地质意义。
In the survey of regional geology and minerals with a scale of 1 ： 50000 in the area of Yiwu coal mine, abundant lenticular calciferous nodules are firstly found from former defined Yaomoliang Formation of the upper Carboniferous which bear evident sedimentary feature of continental alluvial fans; plentiful spore and pollen determined the stratum is of upper Permian, consequently former one is renamed to the Kulai Formation. Its age is defined to upper Permian, and geologic significance is initially treated.
