Microcline is one of the most common minerals in Earth’s crust, a variety of feldspar that distinctly shows two planes of cleavage. The larger hand specimen provides excellent visibility of crystal faces, cleavage planes, and surface characteristics. Ideal for geology classroom identification exercises and discussions of Bowen’s reaction series. Supports Next Generation Science Standards.
