| 摘 要： | 为查明东海DC-2孔岩芯中有机质含量的变化情况,对沉积物中有机碳和沥青总量进行了分析测定。在不同深度和不同层位共取了58个样品,由于样品量受到限制,分析沥青的样品重量由250—700克不等。 沉积物的粒度在整个岩芯中变化比较明显,由下而上可分为五个大层。 1.粉砂层(91.5—75.5米):粉砂粒级含

CHARACTERISTICS OF ORGANIC MATTER IN SEDIMENT CORE DC-2 FROM THE EAST CHINA SEA |
| |
| Abstract: | Analysis of organic matter in sediment core DC-2 drilled in the East China Sea shows that. 1. The contents of organic matter and the amount of dissoluble organic matter are-related with grain size. 2. The colour of bitumen can reflect the degree of evolution of organic matter. 3. Sedimentary environment is indicated by the variation of contents of organic matter. 4. Scattered organic matter can not generate petroleum. |
