Plagioclase is the silicate mineral that is found in the greatest variety of igneous rocks. It is a common mineral in both mafic and felsic igneous rocks and can occur in a range of compositions from calcium-rich to sodium-rich. Olivine, pyroxene, and quartz are also common silicate minerals in igneous rocks, but they are not found in as great a variety as plagioclase.
