Physical properties
Hardness of 6-7 (driven by quartz grains), brown to reddish color, dull to granular luster, clastic or fragmental texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments.
Uses & applications
Widely used in construction as a building material, dimension stone, and for paving or landscaping.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossil tracks, offering a window into prehistoric environments.
Field identification & locations
Identified by its gritty texture and visible sand-sized grains; commonly found in sedimentary basins worldwide.
