Physical properties
Hardness 6-7 on the Mohs scale depending on cementation, typically tan, brown, or reddish, dull luster, and granular texture with visible sand grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, over millions of years in desert, river, or beach environments.
Uses & applications
Widely used as a construction material, for building facades, paving stones, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone formations can act as excellent aquifers and reservoirs for oil and natural gas due to their porous nature. Famous landmarks like Petra in Jordan are carved directly into sandstone cliffs.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains. It is extremely common worldwide and very typical for the sedimentary geology of the Midwestern United States.
