5.4 Weathering and the Formation of Soil - Physical Geology

Soil is a complex mixture of minerals (approximately 45%), organic matter (approximately 5%), and empty space (approximately 50%, filled to varying degrees with air and water). The mineral content of soils is variable, but is dominated by clay minerals and quartz, along with minor amounts of feldspar and small fragments of rock.

Difference Between Primary and Secondary Minerals

2020/03/24 · However, the inclusion of a mineral within the category of primary minerals requires the formation of the mineral at early times. An important difference between primary and secondary minerals is that the primary mineral substances are not altered because they form directly from the crystallization of magma.

2. The composition of clay materials | Geological Society

2006/01/01 · Clay materials are composed of solid, liquid and vapour phases. The solid phases are of mineral and organic phases that make up the framework of the clay materials. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called ‘amorphous’ inorganic phases. By definition, minerals are crystalline solids with well-ordered crystal ...

The influence of individual clay minerals on formation

Various processes involving clay minerals are thought to be responsible for formation damage in sandstones. In brief, these include (a) swelling of smectitic clays, (b) dispersion and migration of a variety of clay minerals, including smectites but principally involving kaolinite and illite, and (c) transformation of clay minerals to other ...
