Results show that hydrogen-rich macerals are disintegrated while other macerals like fusain, and exinite are resistant to disintegration.

富氢煤的微组分被分解，而角质等煤的微组分难分解。

Main macerals of hydrocarbon generation are sporinite, cutinite, alginite, bituminite, liptodetrinite and desmocollnite in source rocks from Jurassic coal measure in Northwest China.

西地区侏罗纪煤系地层中主要的微组分是孢子体、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油组分含量很低。
