is a series of tectosilicate (framework silicate) minerals within the feldspar group.

/ˈɡrænɪt/) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.

Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering.

Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), is an important tectosilicate mineral which forms igneous rock.

Sunstone is a plagioclase feldspar, which when viewed from certain directions exhibits a spangled appearance.

intermediate volcanic rock Alkali feldspar granite – A granitoid in which at least 90% of the total feldspar is alkali feldspar Anorthosite – A mafic intrusive.

Moonstone is a sodium potassium aluminium silicate ((Na,K)AlSi3O8) of the feldspar group that displays a pearly and opalescent schiller.

intertwined crystals of quartz and feldspar in the texture known as graphic granite.

Most pegmatites are composed of quartz, feldspar and mica, having a similar.

describing igneous rocks that are relatively rich in elements that form feldspar and quartz.

rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar.

Labradorite ((Ca, Na)(Al, Si)4O8) is a feldspar mineral first identified in Labrador, Canada which can display an iridescent effect.

type of sandstone containing at least 25% feldspar.

Arkosic sand is sand that is similarly rich in feldspar, and thus the potential precursor of arkose.

It is a potassium-rich alkali feldspar.

Oligoclase is a rock-forming mineral belonging to the plagioclase feldspars.

igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene.
