GENERAL GEOLOGY

Detailed explanation-1: -The chemical formula of quartz is SiO2, that is one silicon atom combined with two molecules of oxygen. Quartz is also called as Silica, which is a white or colourless crystalline compound found mainly as quartz, sand, flint and many other minerals.

Detailed explanation-2: -What is quartz? Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, commonly found in nature as quartz. It is the most abundant mineral found at Earth’s surface, and its unique properties make it one of the most useful natural substances.

Detailed explanation-3: -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.

Detailed explanation-4: -Quartz is made of the two most abundant chemical elements on Earth: oxygen and silicon. Atoms of oxygen and silicon join together as tetrahedrons (three sided pyramids). These stack together to build crystals. Billions of tetrahedrons are needed to build even a small crystal.

Detailed explanation-5: -Silica (quartz): Silica, SiO2, is a chemical compound that is composed of one silicon atom and two oxygen atoms. It appears naturally in several crystalline forms, one of which is quartz. Silicon dioxide, commonly known as silica (and/or quartz), is a prevalent element in the Earth’s crust.
