因此，深入研究砂岩成岩作用是分析孔隙水演化过程中离子迁移的重要环节。

Thus, studying sandstone diagenesis is an important link for analysis of ion migration in the evolution of pore-water.

碳酸盐岩次生渗透性是成岩作用、构造作用、水动力作用及生物化学作用的综合结果。

The secondary permeability of carbonate rocks is the result of comprehensive process of diagenesis, tectonics, hydrodynamics as well as of biochemistry.

位于地下水位以下的水。地下水是保存在岩石孔隙中的水，可以是同生水、大气水、或与火成侵入岩体伴生的水。

Water in the subsurface below the water table. Groundwater is held in the pores of rocks, and can be connate, from meteoric sources, or associated with igneous intrusions.
