Physical properties
Hardness: 6-7 (on Mohs scale if quartz-rich), Color: Brownish-red to tan, Luster: Dull or earthy, Crystal structure: Clastic (granular), Cleavage: None, Specific gravity: 2.2-2.8
Formation & geological history
Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments, typically in river beds, beaches, or deserts over millions of years.
Uses & applications
Commonly used in construction for building stone, road base, and as a raw material for glass manufacturing or as a landscaping material.
Geological facts
Sandstone can preserve ancient fossilized ripples from water or sand dunes, providing a record of prehistoric wind and water patterns.
Field identification & locations
Identify by its gritty, sandpaper-like texture and visible sand grains. Found globally in sedimentary basins; look for layered outcrops or riverbed deposits.
