为了研究压溶对原生粒间孔隙的破坏作用,本文为一套沉积层序提出了一个孔隙介质模式。在分析中,对矿物类型、粒径、沉积速率、地温梯度和孔隙水排出等都作了考虑。虽然缝合作用可能是一个重要的胶结因素,但本文只着重讨论埋藏时普遍存在的粒间溶解作用。此外,本文的研究范围也仅限于石英砂屑岩的岩化作用,因为石英砂屑岩的矿物学性质稳定,而且其成岩作用的资料也很丰富。
In order to study the destructive effect of pressure solution on primary intergranular pores, a porous media model was proposed for a set of sedimentary sequences. In the analysis, mineral types, particle size, sedimentation rate, geothermal gradient and pore water discharge were all considered. Although suturing may be an important cementing factor, this article focuses only on the intergranular lysis that prevails during burial. In addition, the research scope of this paper is limited to the lithification of quartz sandstone because the quartz sandstone is stable in mineralogy and rich in diagenesis data.
