Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation; typically tan, brown, yellow, or red; dull to earthy luster; quartz-dominated framework grains.
Formation & geological history
Formed through 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 for manufacturing glass and abrasives.
Geological facts
Famous ancient sandstone structures include Petra in Jordan and the temples of Angkor Wat in Cambodia.
Field identification & locations
Easily identified in the field by its visible sand-sized grains and gritty texture; found globally in sedimentary basins.
