SEQUENTIAL ANALYSIS OF BLACKSHALES AND ITS APPLICATION TO BIOMINERALIZATION RESEARCH

Geoenergy Department, Changchun University of Earth Sciences, 130026 Changchun, Jilin, China

摘要: 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。

Abstract: After leaching blackshales with CHCL₃,HaAc-NaAc buffer,HCl-H₃PO₄ mixture,HCl-HP mix-ture and heavy liquid sequentially,chloroform extracted bitumen-A,carbonate,ferromanganese oxide,silicate components and kerogen are obtained respectively-The recovery of standard addition for different components ranges 86%-104.3%.The sequential analysis is applicable to,besides the study of main components in oil shales,biomineralization research.
