广西十万大山盆地北缘下三叠统中广泛发育有碳酸盐重力流沉积,既有浊流,又有碎屑流及颗粒流.岩性以粗大的砾屑灰岩为主,少量砂屑灰岩。砾屑灰岩共数十层,累积厚百余米。已知分布范围:东自扶绥柳桥,西至宁明梅湾,东西延伸达50公里以上. 研究这种碳酸盐重力流沉积,不仅对沉积环境的研究、岩相古地理图的编制有直接关系,而且在寻找石油、天然气和一些金属矿产方面均有重要意义。 碳酸盐浊积岩也象碎屑浊积岩一样广泛发育。国外已多有报道,国内的研究也逐渐开展起来。
Carbonate gravity flow deposition is widely developed in the lower Triassic of the northern part of Shiwandashan Basin, Guangxi Province, and has both turbid current and debris flow and particle flow. The lithology is dominated by coarse gravelly limestone with a small amount of sand Limestone. Boulder limestone a total of ten layers, the cumulative thickness of more than 100 meters. It is known that the distribution ranges from East Fusui Bridge to west and Ningmingmei Bay to the east and west extends over 50 km.The study of this carbonate gravimetric flow sedimentation not only studies the sedimentary environment and the lithofacies paleogeography Have a direct relationship, but also in the search for oil, natural gas and some metal minerals are of great significance. Carbonatitic turbidites also develop as well as clastic turbidites. Abroad has been more reported, the domestic research is gradually carried out.
