| 中文摘要: |
| 测区原1∶20万巴里坤哈萨克自治县幅区调马依当的一套岩性为陆源碎屑岩夹灰绿、暗灰色富含钙质的火山碎屑岩，将其划归为石炭系下统姜巴斯套组。通过本次对新疆伊吾县伊吾煤矿一带1∶5万区域地质矿产调查，采集到腕足类化石，经鉴定为阔石燕类：Euryspirifer cf及岩石区域对比，与区域上的泥盆系下统托让格库都克组完全可以对比，为该套地层时代重新厘定为泥盆系下统托让格库都克组。新疆伊吾县伊吾煤矿一带泥盆系下统的发现，对该区具有重要的研究意义：本套地层的厘定为（巴里坤地区）北西向构造带（托里—三塘湖晚古生代沟弧带）的发展演化阶段演提供了重要的基础性地质资料）。 |
| 英文摘要: |
| In the Mayidang of 1∶200,000 Bailikun map in the target area, there is a kind of pyroclastic rock which the lithology is grey green or dark gray terrigenous clastic rocks with rich calcium, now it is divided into Jiangbasitao formation of lower Carbonic. In the 1∶50,000 regional geology and mineral survey in Yiwu coal mine, the collected brachiopod is determined to be Euryspirifer type, it can be compared with Tuoranggekuduke formation of lower Devonian in this area, this strata is determined to be Tuoranggekuduke formation of lower Devonian once again. The discovery of lower Devonian in this area has big significance for the scientific study in this area, the determination of this strata affords important geologic information for the NW structural belt evolution. |
