sporinite

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子体、角质体、藻类体、沥青质体、碎屑类体、基质镜质体，而树体、木栓质体低熟生油组含量很低。

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为基质镜质体，少量子体、角质体和碎屑壳质体。
