Coarse sandstone
This reddish rock is arkose, a young feldspathic sandstone. Andrew Alden / Wikimedia Commons. Arkose is a raw, coarse-grained sandstone deposited very near its source that consists of quartz and a significant proportion of feldspar.. Arkose is known to be young because of its content of feldspar, a mineral that usually degrades quickly into clay.Sandstone.

Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone. Sandstone is medium-grained, meaning its fragments are between 1/16 mm and 2 mm. Silt forms fine-grained siltstone, with fragments between 1/16 mm and ...The Permian strata consist of two members.

Coarse sandstone, fine sandstone, and sandy mudstone are favorable for ISL mining in Qianjiadian uranium deposits because their permeability is above the required permeability threshold of ISL.
Coarse sandstone samples were taken from a coal seam roof passed by the Shihuoshan tunnel in Xinjiang, China. The local area of the tunnel passes through a natural coal seam zone.
