Andesite | Geology Wiki | Fandom
Magnetite, zircon, apatite, ilmenite, biotite, and garnet are common accessory minerals. Alkali feldspar may be present in minor amounts. The quartz - feldspar abundances in andesite and other volcanic rocks are illustrated in QAPF diagrams. Classification of andesites may be refined according to the most abundant phenocryst.
Andesite - Assignment Point
Magnetite, zircon, apatite, ilmenite, biotite, and garnet are common accessory minerals. Andesite usually does not contain quartz or olivine. It is typically found in lava flows produced by stratovolcanoes. Because these lavas cooled rapidly at the surface, they are generally composed of small crystals.

Andesite: Mineral information, data and localities.
When porphyritic, andesite rocks contain phenocrysts composed primarily of zoned sodic plagioclase (esp. andesine) and one or more mafic minerals (e.g., biotite, hornblende, pyroxene, usually <20%), with a groundmass composed generally of the same minerals as the phenocrysts, although the plagioclase may be more sodic, and quartz is generally present in small amounts.
