藻类体
The organic source rocks of Paleogene from Huangxian basin are rich in the content of exinite and sapropelinite,especially resinite and alginite. 黄县盆地下第三系有机岩中含有丰富的壳质组和腐泥组,尤其发育树脂体和藻类体,这些富氢组分的荧光性质各不相同。
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。
