| 摘 要： | 由于大多数沉积有机质或煤层中的木栓质体在很低演化阶段荧光就消失了，使得地球化学家和煤岩学家往往低估了木栓质体对成烃的贡献。利用显微镜荧光检测和显微傅里叶红外光谱技术对现代植物栓皮栎的树皮进行人工热模拟研究，结果表明现代木栓组织和木检质成分是一种高度偏油的有机质，在低热力条件下释放出大量的以异构烃和环烷烃为主的液态烃类，大约在镜质体反射率为０．５％之前，生成Ｃ６＋烃类总量的２／３以上。现代木栓热模拟生烃现象要滞后于地质体中的木栓质体，它不能完全复制木栓质体的自然熟化过程

| Abstract: | The contribution of suberinite on the hydrocarbon generation is often underestimated by the geochemists and coal petrologists due to that the fluorescences of the suberinites in most sedimentary organic matters or coalbeds are eliminated in lower evolutional stages.The artificial thermal simulation on the bark of recent Quercus suberus is studied by means of the microfluo ronetry and micro-Fourier infrared spectroscopy.The result indicats that the recent subereous component is an organic matter which has a great trand to generate oil,releases a lot of liquid hydrocarbons dominated by isomeric hydrocarbon and cycloparaffinic hydrocarbon under lower thermodynamic condition,and generates more 2/3 of C 6 hydrocarbons before the vitrinite reflectance of 0.5%.The hydrocarbon generation by thermal simulation of recent subereous component lags behind that of suberinite in geologic bodies,it could not ripeat fully the natural mature history of the suberinite. |
