By taking pyrolysis experiments and analyzing composition and carbon isotopes of pyrolysis products,the hydrocarbon generation potential and products of very low-grade epimetamorphic rocks were studied.
以松辽盆地为例,通过热模拟实验及热模拟产物组分和稳定碳同位素分析,对极低级浅变质岩(泥板岩)的生烃能力及产物进行研究。
2) diagenesis and very low grade metamorphism
成岩-极低级变质作用
5) low-grade metamorphic zone

1.
This paper overviewed the recent progress of the studies on very low-grade metamorphism and presented a new frame for the division of diagenetic-very low grade metamorphic-low grade metamorphic zones based on a quantity of data.
介于成岩作用与低级变质作用之间的极低级变质作用是一个重要过程 ,对于全面认识地球浅层动力学与成矿作用有重要意义。
2.
The major progresses of very low-grade metamorphism are as follows: very low-grade metamorphic belts have been subdivided into Early diagenetic zone, Late diagenetic zone, Low anchizone, High anchizone, Epizone through integrally using of XRD and TEM techniques.
近年来国际上极低级变质作用的研究进展包括综合运用了伊利石结晶度等各项指标 ,将极低级变质带划分为成岩带、近变质带和浅变质带 ,成岩带和近变质带又可进一步划分为低级成岩带、高级成岩带、低级近变质带和高级近变质带 ;研究了伸展背景、阿尔卑斯碰撞背景和增生背景下的极低级变质作用 ;进一步理解了矿物的转变过程 ,建立了变质泥质岩石的矿物反应系列。
