古生界海相烃源岩中芳烃生物
1.Presented in this study are the characteristics of aromatic hydrocarbon biomarkers in the Lower Palaeozoic marine carbonate rocks in North China, including phenanthrene, biphengl, benznuorene,benzfhiore tri-fluorene, fluoranthene series pyrene, benz fluoranthene series beamperylene, chrysene and triaromatic sterane. The content of naphthalene is relatively low.
2.Occurrence of High Mature Organic Matter in Marine Black Shale Source Rocks of Lower Cambrian from Northern Tarim Basin,China
5.The geochemical characteristics of extract from the source rocks,such as organic matter composition of saturation hydrocarbon(based on gas chromatogram),composition and configuration characteris tics of steroid and triterpane(based on GC/MS),and carbon isotopes composition of chloroform bitumen A and group composition have been presented too. According to the geochemical characteristics of organic matter in source rocks,the parent matter type,geochemistry en-viron ment and maturity of organic matter were analyzed.
7.GEOCHEMICAL METHODS AND RESEARCH STATUS QUO ON LOWER PALAEOZOIC MARINE CARBONATE HYDROCARBON-GENERATING ROCKS
8.According to the differences of sedimentary facies and environment, the source rock are divided into four types such as lime-mud reef in platform margin, platform inner sag, deep-water flat slope or continental shelf, abyssal basin, the lime-mud reef type is distributed in platform margin of Upper Ordovician, the remained three types are widely distributed in Cambrian-Ordovician system.
