晚二叠世龙潭煤系是湘赣地区的重要含煤地层。可采煤层主要分布在煤系地层上段, 该段地层在湘中、湘南称为资家台亚段;在赣中称为老山组。本文运用含煤亚段地层中“沉积体”的产状、岩性和岩相的综合资料,试对湘中、湘东、湘南和赣中地区龙潭煤系晚期的成煤古地理环境加以梗概探讨。
The late Permian Longtan coal measure is an important coal-bearing formation in the Hunan-Jiangxi region. Coal mining is mainly distributed in the upper strata of coal measures, this section of strata in Hunan, Shonan called Ziya Taiwan sub-section; in Jiangxi called Laoshan group. In this paper, using the comprehensive data of the “sedimentary bodies” in the coal-bearing sub-strata of the “sedimentary body” in the coal-bearing formations, the coal-formed paleogeographic environments of the Late Lungtan Coal Measures in central Hunan, eastern Hunan, southern Hunan and Jiangxi provinces To outline the discussion.
