maceral

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

结果表明：富氢的显微组分被分解，而丝炭和角等的显微组分难分解。

The main hydrocarbon-generating macerals in the source rocks of the coal measures are exinite, alginite and desmocollinite.Organic matter is dominantly of type III kerogen.
