Associated minerals include garnets, vesuvianite, diopside, tremolite, epidote, plagioclase feldspar, pyroxene and calcite. The mineral assemblage is typically dominated by plagioclase plus pyroxene or hornblende. The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. It can be found in igneous rocks containing potassium feldspar and plagioclase. Phenocrysts include augite, labradorite, olivine and plagioclase; additionally spinels are found in the rocks. Albite is considered both a plagioclase and alkali feldspar. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar. Anorthite is the calcium endmember of the plagioclase feldspar mineral series. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. True granite (according to modern petrologic convention) contains both plagioclase and alkali feldspars. Solid solutions between albite and anorthite are called "plagioclase", or more properly "plagioclase feldspar". Proterozoic anorthosites often have significant mafic components in addition to plagioclase. Wishstone contained a great deal of plagioclase, some olivine, and anhydrate (a sulfate). Minerals contained in Erciyes rocks include clinopyroxene, ilmenite, orthopyroxene, plagioclase, and titanomagnetite. There, they collected black and white breccias and smaller, crystalline rocks rich in plagioclase.
