Microcline is a common mineral belonging to the feldspar group, primarily composed of potassium aluminum silicate. It typically appears in shades of green, pink, or white and has a glassy luster. Microcline is often found in igneous rocks, such as granite, and can also occur in metamorphic rocks. This mineral is significant in geology and is used in various applications, including ceramics and glassmaking. Microcline can also contain inclusions of other minerals, such as quartz and muscovite, which can enhance its aesthetic appeal in decorative stones.
