| 摘 要： | 云南省富源县老厂矿区是我国南方重要煤炭基地——六盘水煤田的一个组成部分,地处云南省富源县老厂乡。本文通过古构造古地理背景及沉积组合分析,主要探讨了该区龙潭组第三段沉积环境及其聚煤作用,认为该区龙潭组总体上表现为一个大的海退层序,几层主要可采煤层都是在下伏沉积废弃后发生泥炭沼泽化形成的,其聚集的过程与下伏沉积物的沉积环境有直接或间接的联系。

| Abstract: | Laochang mining field is a part of Liupanshui coalfield which is an important coal base of south China,the location is Laochang of Fuyuan county,Yunnan province.By analysis the palaeostructure and palaeogeographic background and sedimentary association,the depositional environment and coal accumulation of the third member,Longtan formation of this region are studied in this paper,it's thought that the Longtan formation showed as a big regressive,several workability seams formed by the happening of peat swamp after the subjacent sediment discarded.The process of accumulation has direct or indirect relationship with sedimentary environment of subjacent sediment. |
