利用共聚焦激光显微镜和透射电镜对吐哈盆地侏罗系煤进行超微层次有机岩石学分析，发现微米级以下超微类脂体普遍存在于无结构镜质体和一些粗粒体之中。常规光学显微镜下难以分辨超微类脂体，在镜质体反射率Ｒｏ０．５０％～０．７０％时，煤中超微类脂体数量一般为８％～１２％。超微类脂体的光性演化明显领先于壳质组形态组分孢子体和角质体，它是吐哈侏罗系煤中重要的生油组分。
Using confocal laser scanning microscopy and transmission electron microscopy on the Jurassic coal in the Turpan-Hami basin, an ultrahierarchical organic petrological analysis was conducted. It was found that the ultramicro lipid bodies below the micron level were commonly found in unstructured vitrinites and some coarse grains. Conventional light microscopy is difficult to distinguish ultramicro lipids, the vitrinite reflectivity Ro0.50% ~ 0.70%, the amount of coal in the ultramicro lipid body is generally 8% to 12%. The phototactic evolution of the superthin liposomes significantly preceded the sporophyte and the horny body of the morphological components of the chitin group, which is an important oil-producing component of the Tuha Jurassic coal.
