Physical properties
Hardness of 6-7 on the Mohs scale, tan to reddish-brown color, dull to earthy luster, clastic texture composed mostly of quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, beach, or river environments over millions of years.
Uses & applications
Widely used in construction as a building and paving material, as well as in the manufacture of glass and abrasives.
Geological facts
Sandstone often preserves ancient ripple marks and cross-bedding, providing geologists with clues about past environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains; found abundantly worldwide in sedimentary basins.
