摘要
全文介绍了国外在近几十年中对抱粉相研究的发起、深入和逐步趋向完善。通过研究薄片中各抱粉有机物质的百分含量、保存状况以及一些具特殊指相意义的孢粉类别，利用图示法将它们表示出来，最终与几种海相页岩沉积相分别对应起来。这方面的工作无疑会推动地质学领域内其它学科的发展。
The author introduces the recent progress in the field of palynology and its influence on the oil industry as well as sedimentary environments study. The palynofacies aims at the detailed study of palynological organic matter in sedimentary rocks. Microscopic sin dies of sedimentary organic matter in slides are used for (1) prelimiary determination of hydrocarbon source rock potential. (2) deriving correlation at levels below biostratigraphic resolution (3) palaeoenvironmental interpretation.The palynofacies analysis is both qualitative and quantitative. Qualitatively, it involves the environmental interpretation of organic matter types. The quantitative study includes identification of various groups of morphological similar constitutes under transmitted lightand the estimation of the relative and absolute abundance of these groups. Results are.graphically presented in two kinds of diagrams: a. compositional percentage distribution diagram; b. AOM--phytoclast-palynomorphs plot of ternary diagram of percentage particleabundance to characterize palynological organic matter into ten (independently sedimentologically--defined) marine shale factes.
