In the process of unconventional Ba enrichment, a lot oforganic carbons were depleted and the maturityoforganicmatter became higher.
钡的超常富集，不仅是一个消耗大量有机碳的过程，而且是有机质成熟度不断加深的过程。

It is the most important that source rocks tectonic heated history to maturityoforganicmatter and controls on the hydrocarbon generation of source rocks.
烃源岩的构造-受热史是有机质成熟演化、烃源岩生烃演化的最重要控制因素。

In this paper, the organic geochemical characteristics of the hydrocarbon source rocks are described in detail in the light of the abundance, type and maturityoforganicmatter.
