有机岩石学全岩分析结果表明，江汉盆地盐湖相烃源岩显微组分含量明显偏低，平均仅占全岩体积的１．５％。显微组分组成中富含腐泥组、贫惰性组、相对发育镜质组和壳质组，具有藻类低等生物与高等植物混合生源的特点。藻类体是江汉盆地低熟油的主要生烃组分，隐含于矿物沥青基质中的有机质约占总有机质的一半以上，是江汉盆地值得重视的生烃组分
The results of the whole rock analysis of organic petrology show that the content of the microscopic components of the salt source rocks in the Jianghan Basin is obviously low, averaging only 1.5% of the volume of the whole rock. The microscopic composition is rich in sapropel group, poor inert group, relative developmental vitrinite and chitin group, which has the characteristics of low algae mixed with higher plants. Algae bodies are the major hydrocarbon-generating components of low-mature oil in Jianghan Basin. The organic matter implied in the mineral bitumen matrix accounts for more than half of the total organic matter, which is a significant hydrocarbon generating component in Jianghan Basin
