Physical properties
Hardness 6-7 on Mohs scale, tan to brown color, dull earthy luster, clastic texture composed mostly of quartz 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, masonry, paving, and as a decorative building stone.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, acting as natural aquifers and reservoirs.
Field identification & locations
Readily identified in the field by its visible granular sandy texture and gritty feel; common worldwide in sedimentary basins.
