摘要
Mineral-bituminous matrix (MBM) makes up a major part of source rocks, but itspotential in hydrocarbon generation is uncertain. Mineral and organic (maceral and kerogen)compositions, organic maturity and fluorescence of MBM are studied based on source rock samples from eastern Jiuquan (Jiudong) Basin. The results show that MBM is dominated by inorganic minerals and among the small percentage of organic components those of secondary originsare predominant over the primary species. This strongly indicates that the significance of MBMin hydrocarbon generation is limited.
