| 摘 要： | 四川盆地西南晚三叠世含煤地层为四川省重要的含煤地层,在该地区工作的各地勘单位对含煤地层的划分和命名存在较大差异。通过区域资料的分析对比,进行了含煤地层划分和煤层对比初步研究,认为垮洪洞组和小塘子组向东尖灭,须家河组一段由东向西超覆,不同命名的K7与高炭、K3与大白炭、K2与小白炭、K1与下元炭为同一煤层或层位。

| Abstract: | Upper Triassic coal-bearing stratum is one of important coal-beating strata in Sichuan basin. Upper Triassic coal-bearing stratigraphic division and correlation based on regional data indicate that the Kuahongdong and Xiaotangzi Formations are pinching out eastward and the Xujiahe Formation is overlapping westward. K7 and Gaotan, K3 and Dabaitan, K2 and Xiaobaitan, K1 and Xiayuantan are the same coal bed or horizon. |
