摘要
The middle and late Darriwilian to the early Katian (Ordovician) sedimentary strata dominantly consist of the Yanxi and Modaoxi formations in central Hunan Province, and Baimachong and Shuangjiakou formations in southern Hunan Province, and may be divided into continental shelf facies, basin facies and continental shelf-margin facies. The continental shelf facies is made up of sandy slate, sandstone, black shale and siliceous rocks. The above-mentioned rocks have higher contents of organic matter, and greater hydrocarbon potential, and thus are believed to be the key horizons for further petroleum exploration.
