Albite is a common mineral belonging 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 applications, including ceramics and glass production. Its presence can help geologists understand the conditions under which rocks formed, making it an important indicator in the study of petrology and mineralogy.
