続成作用におけるスメクタイト-イライト変換反応に影響を及ぼす因子

抄録

Current understanding of factors governing the smectite-to-illite conversion during diagenesis is reviewed in this paper. The factors concerned here are as follows: temperature, pressure, kinetics, Kavailability, inhibitor ions, residence time, origin of starting materials, composition of reaction solution, and porosity and permeability of rocks (and rock/water ratio). Quantitative estimation of the relations between the above factors has not yet been enough. It seems to be necessary to investigate the entire process of smectite-to-illite conversion during diagenesis in close relation to the basis history.
