用三氯甲烷、醋酸－醋酸钠缓冲溶液、盐酸－磷酸混合液、盐酸－氢氨酸混合液和重液分离法，依次处理暗色泥质岩，分别得到氯仿沥青A、碳酸盐组分、铁锰氧化物组分、硅酸盐组分，最后得到生油母质干酪根。各组分的标准加入回收率为38％～104．3％。除用于油页岩中主要组分的赋存状态研究外，该分析方法亦适用于生物成矿作用研究。 The dark mudstone was treated sequentially with trichloromethane, acetic acid-sodium acetate buffer solution, hydrochloric acid-phosphoric acid mixture, hydrochloric acid-ammonia mixture and heavy liquid separation method to obtain chloroform bitumen A, carbonate components, Iron-manganese oxide component, silicate component, and finally kerogen kerogen. Standard components of the recovery rate of 38% to 104.3%. In addition to the study of the occurrence of major components in oil shale, this method is also suitable for the study of bio-mineralization.
