General considerations. Silica minerals make up approximately 26 percent of Earth’s crust by weight and are second only to the feldspars in mineral abundance. Free silica occurs in many crystalline forms with a composition very close to that of silicon dioxide, 46.75 percent by weight being silicon and 53.25 percent oxygen.Quartz is by far the most commonly occurring form.

Silica | IMA Europe

Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth’s crust. In spite of its simple chemical formula, SiO2 , silica exists in many different forms. Silica is found commonly in the crystalline state but occurs also in an amorphous state resulting from weathering or plankton fossilisation.
