Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation; typically tan, brown, or gray; dull to earthy luster; composed of cemented quartz and/or feldspar grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in environments like deserts, rivers, and beaches.
Uses & applications
Widely used in construction as a building stone, paving material, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can be millions of years old and are famous for preserving ancient fossil tracks and wind-blown dune structures.
Field identification & locations
Identified by its distinctly gritty, sandpaper-like texture and visible mineral grains; found globally in desert regions and ancient riverbeds.
