arkose

   Also found in: Dictionary/thesaurus, Acronyms, Wikipedia 0.01 sec.

arkose

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.

arkose [′är‚kōs]
(petrology)
A sedimentary rock composed of sand-size fragments that contain a high proportion of feldspar in addition to quartz and other detrital minerals.
arkose
Sandstone containing 25% or more feldspar grains in abundance; used as building stone.
