| 摘 要： | 对吐鲁番-哈密等盆地100多块煤样有机岩石学分析表明:新疆早中侏罗世煤中普遍含有木栓质体.木栓质体在煤有机显微组分中所占比例仅以木栓化细胞壁计.一般在2%以下,若包括木栓化细胞壁和充填在胞腔中的团块镜质体两部分则最高可达20%.在镜质体反射率0.35%~0.70%时,木栓质体光性发生明显变化,但其形态和数量没有显著变化,反映了木栓化细胞壁中木栓质和蜡质在低成熟阶段明显失去,而作为细胞壁格架的纤维素、木质化纤维素则没有显著变化.随热成熟作用木栓质体光性逐渐向结构镜质体和均质镜质体演化;至镜质体反射率0.90%时二者已难以分辨.

| Abstract: | Suberinite occurs commonly in Jurassic coals of Xinjiang,which is formed from suberized cell walls,particularly in plant periderm.The proportions of suberinite in organic macerals are generally less than 2% if only suberized cell walls are counted,and maximize about 20% if both suberized cell walls and corpocollinite which are contained within the cork cells are conned,In vitrinite reflectance range of 0.35%0.70% R.severe optical changes of suberinite are demonstrated,but its' changes in morphography and content are insignificant.Those phenomena reflected that the suberin and wax fractions in suberized cell walls were obviously lossed in this stage,and the lignified cellulose and cellulose fractions as skeleton of cell walls were demonstrated indistinct changes. Suberinite are progressively evolved to telinite or telocollinite in optical properties during thermal maturation, upon to 0.90% VR,suberinites were impossibly to be identified. |
