Albite is a common mineral that belongs to the feldspar group, primarily composed of sodium and aluminum silicate. It typically appears in a white or light-colored form and has a glassy luster. Albite is often found in igneous rocks, such as granite, and can also occur in metamorphic and sedimentary environments. This mineral plays a significant role in geology and is used in various industrial applications, including ceramics and glass production. Albite can also be an important indicator of the conditions under which a rock was formed, helping geologists understand the history of the Earth's crust.
