His title "Ili Stone" is assigned to a group of mica type minerals that are widely distributed in maritime shale and related sediments. As a result of the depletion of potassium, illite has less potassium and more water molecules than true mica like muscovite, but in any case it has a cloud-like sheet structure and it has a pore in the middle layer and poor It has crystallization. The weathered product of muscovite is illite, which turns into montmorillonite under humid conditions. Illite is a swellable 2: 1 clay mineral known as soil potassium source, also known as potassium-containing mineral (Sharma et al., 2010).
Illite is a 2: 1 clay having a structure similar to smectite, but there is a potassium bridge between the surfaces of clay crystals, the extent of expansion depends on the degree of weathering of potassium. The active surface area is reduced by potassium binding. Illite comes from the modification of Mica which is the main mineral. It is often seen with montmorillonite and its major minerals. It has an unobtrusive CEC. Although chlorite is like vermiculite, occasional loose bonds of hydrated magnesium (such as vermiculite) are replaced with hydrated magnesium sheets firmly bonded to the upper and lower planes. It has two silicon faces, one is aluminum and the other is magnesium; hence it is 2: 2 clay. Chlorite does not swell and CEC is low
Clay mineral composition of different soil layers shows a combination of two different types of clay, namely. (A) Ilit Taurang Stone and (b) Illite - Chrysotile. In the Cantabri village, the combination of illite-warm stone clay mineral indicates that the soil horizon is formed under low temperature and alkaline and reducing conditions. However, other soil layers of the illite-kaolinite clay mineral combination show that the soil can be formed under wet, gentle, and underground conditions. These two soil layers are formed by different parent materials under different geochemical, topographical and climatic conditions.
The soil contains a mixture of various types of clay and it is known that particles agglutinate due to soil salinity. Aggregation is beneficial for soil aeration, root penetration and root growth. Increasing soil salinity may have a positive impact on soil accumulation and stability, but high salinity may also have a bad influence on plants. Contrary to soil salt concentration, sodium concentration in soil is high. Sodium causes soil dispersion and swelling of clay platelets and aggregates. If too much sodium ions are present between the clay particles, the bonded clay particles are destroyed. This separation of clay particles causes them to swell and soil dispersion occurs. As the soil disperses, the clay particles block the pores of the soil and the permeability of the soil decreases. When the soil gets wet and repeatedly dispersed, it solidifies into cementy soil with little or no structure.
