Physical properties
Hardness of 6-7 on Mohs scale due to quartz content; colors range from tan, brown, yellow to red; dull luster; composed of cemented mineral particles or rock fragments.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz and feldspar, in environments such as deserts, rivers, and beaches.
Uses & applications
Widely used in construction as a building material, for paving, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can be millions of years old and often preserve ancient ripple marks and fossilized tracks.
Field identification & locations
Identified by its gritty texture and visible sand grains; commonly found in sedimentary basins worldwide.
