Physical properties
Hardness of 6-7 on Mohs scale. Colors range from tan, brown, yellow, to red due to iron oxides. Dull to earthy luster, composed mainly of cemented quartz and feldspar grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in deserts, rivers, or beach environments over millions of years.
Uses & applications
Widely used in construction as building stone, dimension stone, paving materials, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone formations often create striking geological landmarks like arches and canyons due to differential erosion. Many ancient buildings and monuments globally are constructed from sandstone.
Field identification & locations
Identify by its visible grainy texture like sandpaper and layered bedding structures. Found worldwide in sedimentary basins and arid regions.
