Hydrous desmocollinite and exinite in coal are the principal material for hydrocarbon generation.

另外，本文提出了的有机地化参数类比系数法，生烃潜力进行了评价。

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

富氢的分被分解，而丝炭和角质等的分难分解。

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和腐泥,尤其发育树脂体和藻类体,这些富氢分的荧光性质各不相同。
