| 摘 要： | 根据鄂湘黔桂地区大隆组的岩性组合特征,大隆组可以划分7种沉积类型,它们的岩性、岩相在纵、横向上往往表现为突变.大隆组是晚二叠世海侵期的产物,其沉积物与烃源岩关系非常密切,尤其是厌氧、缺氧环境下的沉积物与烃源岩关系更为紧密.海侵期的沉积物、古斜坡沉积环境及低沉积速率使大隆组具有烃源岩发育和形成的潜力.

| Abstract: | Dalong Formation of Late Permian in Hubei, Hunan, Guizhou and Guangxi in South China could be subdivided into seven sedimentary types according to the lithology, indicative of the great spatial variations of both the lithology and sedimentary facies. Dalong Formation deposited during the highest transgression of Late Permian, showing a strong linkage with the hydrocarbon source rocks, in particular those deposited under the anaerobic and suboxic conditions. Dalong Formation shows potential as hydrocarbon source rocks due to the deposition in the highest transgression sea level, the deep slope sedimentary environments and the low sedimentary rate. |
