Andesine is a mineral belonging to the feldspar group, specifically an intermediate plagioclase feldspar. It is found in volcanic rocks like andesite. Andesine is chemically between albite (a sodium feldspar) and anorthite (a calcium feldspar). It is a rock-forming mineral, meaning it is a common component of many rocks, particularly those of igneous origin. Andesine is often found alongside ferromagnesian minerals such as pyroxene or biotite.1234
