Physical properties
Hardness 6-7 on the Mohs scale, rough granular texture, tan to light-brown color, and dull/earthy luster.
Formation & geological history
Formed through the deposition, compaction, and cementation of mineral particles and quartz sand grains in desert, beach, or riverbed environments.
Uses & applications
Commonly used as building stone, paving material, architectural aggregate, and as a reservoir rock for water and hydrocarbons.
Geological facts
Sandstone makes up roughly 20-25% of all sedimentary rocks on Earth's crust and preserves vital records of past environments.
Field identification & locations
Identified in the field by its distinct gritty, sandpaper-like feel and visible cemented sand grains; abundant worldwide.
