Introduction to Clay Minerals Soils

Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

Pyroxene Wikipedia

The chain silicate structure of the pyroxenes offers much flexibility in the incorporation of various cations and the names of the pyroxene minerals are primarily defined by their chemical composition. Pyroxene minerals are named according to the chemical species occupying the X (or M2) site, the Y (or M1) site, and the tetrahedral T site.

Need some help How do silicate minerals chemically

Depends on the mineral. Generally you have something like the classic serpentenite reactions 3 Fe2SiO4 2 H2O → 2 Fe3O4 3 SiO2 2 H2. So you're taking very mafic neso- or ino-silicate minerals (volcanic stuff) and breaking them up into metal oxides and cyclo-, tecto- or phylo-silicates.
