Physical properties
Hardness of 6 to 7 on Mohs scale depending on cement; colors range from tan, brown, yellow to red; dull luster; granular texture composed mainly of quartz and feldspar grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building material, dimension stone, paving, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, making them crucial reservoir rocks for aquifers and oil fields.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains; commonly found in sedimentary basins and exposed cliff faces worldwide.
