Physical properties
Hardness 6-7 on Mohs scale; rough, earthy brown to tan color; dull luster; clastic granular texture composed primarily of quartz grains.
Formation & geological history
Formed through the weathering, deposition, and lithification of sand-sized mineral particles over millions of years in desert, river, or beach environments.
Uses & applications
Commonly used in construction as aggregate, paving stone, building material, and decorative landscaping rock.
Geological facts
Sandstone preserves ripple marks, cross-bedding, and fossils that record ancient surface environments and climate shifts.
Field identification & locations
Identified in the field by its gritty, sandpaper-like texture and visible sand grains under magnification; abundant worldwide in sedimentary basins.
