| 摘要: |
| 气相色谱分析表明,原生包裹体内存在着数种烃类诸如CH4,C2H4,C3H8,C3H6,C2H2,iC4,nC4,iC5,nC5和C6。轻烃的干湿比很高(0.972~0.998),具有煤型气的特征。流体包裹体常沿着愈合断裂与煤包裹体共生,由此推断成矿流体内的轻烃可能来自于煤而非石油。 |

| Abstract: |
| Gas chromatographic data show that there are several species of hydrocarbons such as methane, ethene, propane, propylene, acetylene, isobutane, normal butane, isopentane, normal pentane and hyxane in primary aqueous inclusions. The dry-wet ratio of light hydrocarbon is very high (0.972~0.998) which is characteristic of coal-type gas. It can be considered that the light hydrocarbon in the fluid inclusions associating with coal inclusions along some healing fractures may derive from coal instead of petroleum during coalification. |
