如果考虑土壤物质的长期稳定性，就必须考虑物理、化学和生物作用产生的自然矿化过程。由于这些作用，矿物的沉淀、溶解和再沉淀将改变土壤的孔隙分布、强度、渗透性等方面的微观结构。在土壤颗粒之间的接触处沉淀的矿物可能起到重要的胶结剂作用，而结核的形成将使土壤不均匀。另一方面，矿物的溶解产生非常大的孔隙。它可能会导致土壤的高渗透性。因此，本文对各种条件下的自然成矿作用进行了描述，并对某些关键部位（如深埋地）成矿的可能性进行了探讨。
If a very long-term stability of soil materials is concerned, it is necessary to consider natural mineralization processes resulting from physical, chemical and biological actions. Precipitation, dissolution and reprecipitation of minerals due to these actions will change the microstructure of soils in terms of void distribution, strength, permeability, etc. Precipitated minerals at the contacts between soil particles may play an important role as cement agent, while the formation of nodules will make soils unhomogeneous. On the other hand, dissolution of minerals produces very large pores. It may cause high permeability of the soils. Therefore, this paper describes natural mineralization under various conditions and discusses the possibility of mineralization in some crucial site, such as a deep excavated-buried ground.
