Physical properties
Hardness of 6-7 on Mohs scale, typically brown, tan, or reddish with a granular texture and dull luster.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, mostly quartz and feldspar, over millions of years.
Uses & applications
Commonly used in construction, building facades, paving, and decorative landscaping.
Geological facts
Sandstone formations can act as aquifers for groundwater storage and are often host to petroleum reserves.
Field identification & locations
Identify by visible sand-sized grains and gritty texture, found globally in deserts, riverbeds, and ancient marine environments.
