Grus (geology)
Appearance
Grus is an accumulation of angular, coarse-grained fragments (particles of sand and gravel) resulting from the granular disintegration by the processes of chemical and mechanical weathering of crystalline rocks (most notably granitoids) generally in an arid or semiarid region.[1] Grus sand, when cemented into a sandstone, will form an arkose.
