Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation. Colors range from tan, brown, yellow, red, to gray. It has a dull, earthy luster and a clastic texture.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, mainly quartz and feldspar, in marine, desert, or river environments.
Uses & applications
Commonly used in construction, as a building and paving material, and in landscaping.
Geological facts
Sandstone formations often preserve ancient ripple marks and dinosaur footprints, providing valuable clues about prehistoric environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains. Found worldwide in sedimentary basins and escarpments.
