The silicon-oxygen tetrahedron is the building block of silicate minerals. The word "silicate" means the compound contains silicon in some form.
the basic block of the silicate minerals are formed from rocks.

SiO2 is the basic building unit of silica.
Silicate tetrahedra. The tetrahedra are spanned by oxigen atoms, and right in the middle, there is a silicon atom. The chemical formula for one silicate tetrahedron is SiO4 The actual rate between silicon and oxigen can change as the tetrahedra are linked together, as different tetrahedra can share an oxigen atom with eachother.

One common method of classifying minerals is by their basic group, thus silicates, carbonates, sulfides, phosphates, and so on. Thus you may have a copper carbonate, a silicate, a sulfide and so on.

Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.
