孢粉[子]体,[地质]孢壁煤素质
Alginite and sporinite is suggested to be main macerals of hydrocarbon generation.Based on the study, a hydrocarbon generation model of source rocks in Subei basin is established. 确认藻类体和孢子体为其最主要的生烃组分，在此基础上建立了苏北盆地下第三系烃源岩的生烃模式。
A small quantity of sporinite and cutinite were identified in addition to the majority of the hydrocarbon-forming micro-components that mainly occurred as matrix vitrinites. 烃源岩主要生烃显微组分为基质镜质体，少量孢子体、角质体和碎屑壳质体。
Main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollnite in source rocks from Jurassic coal measure in Northwest China. 西北地区侏罗纪煤系地层中主要的生烃显微组分是孢子体、角质体、藻类体、沥青质体、碎屑类脂体、基质镜质体等，而树脂体、木栓质体等早期低熟生油组分含量很低。
