Physical properties
Hardness: 6-7 (depending on quartz content), Color: Varies from tan, brown, yellow, red, grey to pink, Luster: Dull or earthy, Crystal structure: Clastic (composed of mineral particles or rock fragments cemented together), Cleavage: None
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, typically in environments like deserts, rivers, and beaches.
Uses & applications
Used widely in construction as building material, paving stones, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone formations can be very durable and form many famous geological landmarks and monuments around the world, such as Petra and parts of the Grand Canyon.
Field identification & locations
Easily identified by its gritty texture and visible sand-sized grains; commonly found in sedimentary basins worldwide.
