Crystalline silica is the scientific name for a group of minerals composed of silicon and oxygen. The term crystalline refers to the fact that the oxygen and silicon atoms are arranged in a three dimensional repeating pattern. ... Because oxygen is the most abundant element in the Earth’s crust and silicon is the second most abundant, the formation of silica is quite common in nature. … quartz, … is the most common form of silica found in nature. Silica can also be biological in origin, produced by tiny organisms. The most significant of these are diatoms (plants) and radiolarians (animals) ... Thus, silica can be found in more than one state—amorphous as in the remains from a diatom and crystalline as in a quartz crystal … Both are SiO2, but they are quite different physically. 3, record 3, English, - crystalline%20silica

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.
