Sandstone description

Sandstone. The description of Sandstone can be split into two parts, the properties of the whole rock, and the properties of the grains that make up that rock. a) Rock Name Sandstone or Sand. Sandstone is composed of cemented Sand grains, but be aware that bit action can reduce even reasonably well cemented Sandstone to a tray full of grains.
