显微煤岩组分分析表明，吐哈盆地侏罗纪煤层中富含弱荧光镜质体，从而增强了煤成烃潜力。显微煤岩类型以微镜煤和微镜惰煤为主，它们形成于深覆水沼泽相。高等植物和低等植物的菌藻类都参与了聚煤作用，细菌活动强烈，并导致形成大量生物降解体和原生黄铁矿。深覆水低位沼泽、草本或低等成煤植物以及强烈的细菌活动是荧光镜质组形成的必要条件。煤成烃潜力取决于壳质组分和荧光镜质体的含量。 Micro-coal and rock component analysis shows that Jurassic coal seams in Turpan-Hami Basin are rich in weakly fluorite vitrinite, which enhances the potential for coal formation. The types of micro-coal and rock are dominated by micromirror coal and micromirror inert coal, which are formed in the deep overlying swamp phase. Bacteria and algae from higher plants and lower plants are all involved in coal-accumulating processes with strong bacterial activity leading to the formation of large numbers of biodegradable bodies and native pyrite. Deep-lying low water bogs, herbaceous or low-grade coal-forming plants and strong bacterial activity are essential for the formation of a fluoroscopic vitrinite. The potential for hydrocarbon formation depends on the content of the chitin component and fluorophore.
