ARKOSE


Meaning of ARKOSE in English

n.

Coarse sandstone that has formed by the disintegration of granite without appreciable decomposition.

It thus consists primarily of quartz and feldspar grains. In the absence of stratification, arkose may bear superficial resemblance to granite, and it sometimes has been described as reconstituted granite, or granite wash. Like the granite from which it was formed, arkose is pink or gray.
