摘要
本区寒武—奥陶系碳酸盐岩的成岩后生作用主要有:白云岩化作用、胶结作用、去膏化和去白云岩化作用、重结晶作用、压溶作用和溶解充填作用等。其中白云岩化,去膏化和溶解作用常增大岩石中的孔隙空间,对岩溶水的储渗有利;而胶结作用、重结晶作用和充填作用常降低岩石中的孔隙空间,对岩溶水的储渗不利。本文还根据各成岩作用产生的时间及其相互关系,总结了成岩阶段和成岩序列。
This paper makes a detailed study on the diagenetic and deuterogenic process of the Cambrian-Ordovician carbonate rocks in Jiaozuo area of Henan province, including dolomitization, cementation, degypsumization-dedolomitization, recrystallization, pressurizes dissolution and dissolution-filling process.The results of study shows pore space will be enlarged by the processes of dolomitization, degypsumization-dedolomitization and dissolution, which is favourable for storage and permeability of karst water, but will be decreased by cementation, recrystallization and filling, which is quite unfavourable.The paper also makes a summary of diagenetic stages and diagenetic sequence on the basis of the corresponding rock-formings times and interrelations.
