Physical properties
Mohs hardness: 6-7; Color: tan, yellow, or brown; Luster: dull/earthy; Texture: clastic/gritty; Specific gravity: 2.2-2.8.
Formation & geological history
Formed by the accumulation and cementation of sand-sized grains, typically quartz or feldspar, in environments such as beaches, deserts, or river beds.
Uses & applications
Used extensively as a building material, in glass manufacturing, for paving, and as an abrasive.
Geological facts
Sandstone is highly porous and acts as a major reservoir for groundwater and petroleum; it often contains beautiful cross-bedding structures.
Field identification & locations
Identified by its gritty feel (like sandpaper) and visible sand grains. Found globally in canyon walls and outcrops. Look for layered structures.
