Arkose or arkosic sandstone is a detrital sedimentary rock, specifically a 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. Quartz is commonly the dominant mineral component, and some mica is often present.

Volcanic rocks in Grandfather Mountain Formation belong to informal Crossnore plutonic-volcanic group. Gross stratigraphy resembles that of Mount Rogers Formation. Arkose is normally grey to reddish in colour. The sand grains making up arkose are usually coarse. Arkose is generally formed from the weathering of igneous or metamorphic rocks. These are usually granite rocks, which contain a lot of feldspar and quartz. Arkose is often found with conglomerate deposits where the sediment is made of granite.
