【摘要】 本文根据高分辨电镜观察结果,描述了若干前寒武纪干酪根的微结构,讨论了干酪根微结构与母岩变质作用的关系。发现,在变生和变质过程中,干酪根微结构的变化趋势是不同的;层间距(d₀₀₂)不是H/C比值的线性函数;干酪根的微结构可以指示母岩的变质程度。更多还原

【Abstract】 Presented in this paper are the results of HRTEM observations of microstructures of several Precambrian kerogens. The microstructural characteristics of these kerogens are described and the relationship between the microstructures of kerogens and the metamorphism of host rocks is also discussed, Different trends have been observed with respect to the variation of microstructures of kerogens in the processes of metagenesis and metamorphism. The interlayer spacing (d₀₀₂) is not a linear function of the H/C ratio. And there is a possibility that the microstructure of kerogen can reflect the metamorphic grade of its host rock.更多还原
