| 摘 要： | 长期以来,我国华南地区二叠纪的成煤时代,一般认为只有早三叠世早期的梁山期和晚二叠世早期的龙潭期。后者以含大羽羊齿植物群为特征,所以又常被称为“大羽羊齿煤系”。近年来,随着区调和煤田地质工作的深入开展,华南二叠系研究获得了新的进展,证明了“大羽羊齿煤系”实际上包含了二叠纪不同时期的含煤地层,尤其是华南地区具有工业价值的煤层,并不限于赋存在上述两个含煤地层中。因此,不同成煤期的正确划分,将

| Abstract: | The Permian is one of the main coal-bearing strata in the south China region. According to the recent stratigraphic and paleontological data,the Permian coal measures may fall into the following coal-forming periods: （1） the earliest Permian Liangshanian coal-forming period,which occurred along the northern margin of the Jiangnan oldland; （2）the late Early Permian doulingian coal-forming period,which mainly occurred in the southeastern part of the region; （3）the initial early Late Fermian Shahuian coal-forming period,which only occurred in the Enkaitai area,Guangdong province; （4）the terminal early Late Permian Wangpanliian coal-forming period,which occurred in Leping and Fengcheng of Jiangxi province and Quren of Guangdong prov- ince; （5） the latest Permian Jiupuian coal-forming period,which is the main coal-forming one in Lianyang of Guangdong as well as the southwestern area of the region. From east to west,the coal-bearing levels become gradually high. The distribution and migration of different coal-bearing periods is closely related to the advance and retreat of the seawaters and the paleogeographic position. In the future attention should be paid to looking for the coal beds of the Qiupuian coal-forming period and the buried coal fields of this coal-for- ming period. |
