Physical properties
Hardness: 6-7 on Mohs scale; Color: Tan, beige, light brown, yellow-brown; Luster: Dull, earthy; Grain: Medium-grained, granular sand texture; Cleavage: None.
Formation & geological history
Formed from the accumulation and cementation of sand-sized grains, usually composed of quartz and feldspar, deposited in desert dunes, river channels, or beach environments over millions of years.
Uses & applications
Used extensively as an ornamental landscape stone, building material, garden accent, stacked rock cairn, and paving stone.
Geological facts
Sandstone is one of the most common sedimentary rock types on Earth and makes up roughly 20 percent of all sedimentary rocks found on the planet's surface.
Field identification & locations
Recognized in the field by its gritty, sandpaper-like surface feel and visible quartz grains. Commonly found in exposed rock faces, canyons, and commercially sourced quarries.
