The Sedimentary Environment and Organic Matter Distribution of Marine Clastic Source Rocks
-
摘要: 湖相与海相生烃岩的沉积环境不完全相同。文章根据国内外有关海相生烃岩沉积环境的资料，探讨了富含有机质泥岩的沉积模式。古海洋学、地层层系及浮游有孔虫的研究成果表明环北大平洋地区生烃岩出现的层位及沉积时的古气候有相似性。笔者还应用层序地层学及有机地化资料，讨论了有机质的分布及其控制因素。Abstract: There are some differences in sedimentary environments of continental and marine source rocks, thesedimentary model of organic-carbon-rich mudstones was investigated based on the data of marine sourcerocks at hove and abroad. The research result of paleo-oceanography,stratigraphic sequences and oxygenisotopes of plankton Foraminifera indicated that the organic-carbonich sediments in the north Pacificcoust are of similarity in age and paleodimate, according to the data of stratigraphic sequences andgeochemstry,the distribution and cotrolling factor of organic matter were discussed as well.
