clay Formation Infoplease

12 ensp 0183 ensp One of the commonest processes of clay formation is the chemical decomposition of feldspar Clay consists of a sheet of interconnected silicates combined with a second sheetlike grouping of metallic atoms oxygen and hydroxyl forming a two layer mineral such as kaolinite Sometimes the latter sheetlike structure is found sandwiched between

The Process of Soil Formation

Gleization The term glei is of Russian origin which means blue grey or green clay Gleization is a process of soil formation resulting in the development of a glei or gley horizon in the lower part of the soil profile above the parent material due to poor drainage condition lack of oxygen and where waterlogged conditions prevail

Soil Formation Meaning Factors and Processes

19 ensp 0183 ensp The length of time required for soil formation or genetic horizon development depends upon many inter related factors namely climate nature of the parent materials and relief etc This time span from the inception or zero point of soil development to the present stage is called age of soil Soil formation is a very slow process

Formation damage from swelling clays

Swelling process Clay minerals such as smectites and mixed layer illites can expand in volume up to 20 times their original volume through adsorption of layers of water between their unit cells Such 2 1 clay minerals are particularly prone to swelling because there is no hydrogen bonding between the octahedral layers of the unit cells
