The most frequent reaction causing the self-sealing of rocks with high secondary permeability is argillization . 这种发生频率很高的、使次生渗透性能良好的岩体产生自封闭现象的反应就是泥岩化。
They are free of turbidity, except in some limestone areas and volcanic areas with high secondary permeability where large underground rivers occur . 它们不至于浑浊、只是在灰岩地区和火山地区具有高的次生渗透性并存在大地下河时除外。
