Physical properties
Hardness of 6 to 7 on the Mohs scale, typically brown, reddish-brown, tan, or gray in color, dull to earthy luster, clastic texture composed of sand-sized mineral particles or rock fragments, no visible cleavage.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments (mostly quartz and feldspar) over millions of years, often in desert, river, or beach environments.
Uses & applications
Commonly used in construction, building stone, paving, and manufacturing of glass and concrete.
Geological facts
Sandstone formations can store large amounts of groundwater and petroleum, making them crucial reservoirs for aquifers and fossil fuels. Famous structures like Petra in Jordan are carved directly into sandstone cliffs.
Field identification & locations
Easily identified by its gritty texture, visible sand grains, and layered or massive appearance. Found worldwide in sedimentary basins, deserts, and coastal areas.
