The compositions of organic matter in four immature source rocks from Tertiary strata of Jiyang super-depression, the most typical continental rift subsidence basin in East China, have been stud- ied by different extracting methods with CHCl3, MAC and cs2/nmp, respectively. The results suggest that there are great differences among the chemical compositions of organic matter in the source rocks derived from different depositional environments. About 79% of all the organic matter exists by non- covalent bond in the Es4 source rocks which were deposited under the saline lacustrine, indicating that its organic matter is not the real kerogen, but mainly composed of soluble organic matter which is easy to generate hydrocarbon at lower temperature. This is why the immature oils were derived from Es4 source rocks in Dongying depression. In contrast, around 60% of organic matter exists by covalent bond in Es3 source rocks which were deposited under the deep brackish-fresh lacustrine, showing that Es3 source rocks are mainly composed of kerogen producing mature hydrocarbon at higher temperature. The thermal simulation experiments, upon the remaining solid source rocks which were sequentially extracted by the three solvents, have been carried out. The chloroform extracts from the simulation product have been compared with the other three solvent extracts gained at room temperature. It is obvious that re-markable odd/even predominance (OEP) is mainly the characteristic of soluble organic matter; phytane mostly exists in the soluble organic matter by means of non-covalent bonds and characteristics of soluble organic matter are similar to these in immature oils produced in Jiyang super-depression.

室温下用等体积的二硫化碳／N-甲基-2-吡咯烷酮（cs2／nmp）混合溶剂对灵武煤进行超声辐射萃取。依次用正已烷、苯、氯仿和四氢呋喃作为展开剂对萃取物进行柱层析分离，得到馏分F1～F4，用气相色谱／质谱联用仪（GC／MS）分析各馏分。结果表明，烷烃高度富集于F1中，F3中稠环芳烃相对含量最高，F4的主要成分是合氧有机化合物。
