plagioclase's Usage Examples:

orthoclase and plagioclase feldspars.

As with all plagioclase members, the crystal system is triclinic, and three directions of cleavage are present, two of which are nearly.

gabbroporphyritic partly with very big inclusions of plagioclase, clinopyroxenes and viridescent olivines in partly intersertally, partly intergranularly structured ground.

Anorthosite – A mafic intrusive igneous rock composed predominantly of plagioclase Aplite – A fine-grained intrusive igneous rock type similar to granite.

It has the following mineral assemblages: In metabasites: hornblende + plagioclase ± epidote, garnet, cummingtonite, diopside, biotite In metapelites:.

Myrmekite describes a vermicular, or wormy, intergrowth of quartz in plagioclase.

plagioclase, and 20% potassium feldspar, 7% muscovite, 6% biotite, 1% opaques, and 1% trace minerals.

coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.

a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase.

The main texture in the gabbro is ophitic to sub-ophitic, but hornblende and plagioclase are subhedral to anhedral grains.

(quartz, plagioclase, alkali feldspar) need to be presence to be a granitoid, foid-bearing or feldspathoid rocks, meaning rocks predominantly containing feldspars.

floor of the magma chamber, although they are possible on the roofs if anorthite plagioclase is able to float free of a denser mafic melt.

pyroxene, plagioclase feldspar and accessory garnet, oxides and possibly amphiboles.
