| Abstract: | Organic matter abundances and compositional characters of the soluble organic matter and kerogen of source rocks in some basins of China Seas and adjacent area have been studied according to organic geochemical data in this paper. The organic matter abundances show that content of organic carbon is more than 0.9% in most source rocks and that of Chloroform asphalt "A" is generally greater than 600 ppm and hydrocarbon greater than 200 ppm.
The alkane and pristane/phytane ratio of the source rocks in the studied area may be divided into four association forms. According to abundances of the organic matter, compositional characters of the soluble organic matter and H/C of kerogen, organic matter may be divided into humic-sapropelic and sapropelic-humic types. |
