Question: What Minerals Are Found In Clay? - Ceramics

2020-2-18  Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides (Al2O3, MgO etc.) and organic matter. Where do clay minerals come from? Clays and clay minerals occur under a fairly limited range of geologic conditions.

Soils Clays and Minerals

2021-8-15  Definition: Most soils are composed primarily of minerals, although they often also contain organic materials, especially near the surface where vegetation and its decayed products can be incorporated into soil. Soils are often described in terms of a soil profile which extends from the surface downwards until rock is encountered. The profile often grades from unweathered rock at the base ...
