GEOLOGY

Detailed explanation-1: -Limestone is used to make cement. Quartz is a type of sedimentary rock which is used to make glass. Rock gypsum is used to make plaster. Natural gas, oil, coal, uranium, and other energy resources are formed in and come from sedimentary rocks.

Detailed explanation-2: -Quartz is a defining constituent of granite and other felsic igneous rocks. It is very common in sedimentary rocks such as sandstone and shale. It is a common constituent of schist, gneiss, quartzite and other metamorphic rocks.

Detailed explanation-3: -Quartzite is a metamorphic rock made from quartz sandstone, a sedimentary rock predominantly composed of the silicate mineral quartz. The chemical composite of the quartz minerals is silicon dioxide, written SiO2.

Detailed explanation-4: -Quartz is one of the most common minerals in the Earth’s crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found in all forms of rock: igneous, metamorphic and sedimentary.
