Physical properties
Hardness of 6 to 7 on Mohs scale, reddish-brown color due to iron oxide, dull luster, and a granular texture visible with a hand lens.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in desert or marine environments over millions of years.
Uses & applications
Commonly used in construction as a building and paving material, as well as in landscaping.
Geological facts
Sandstone formations often display distinct parallel layers called bedding planes, which record ancient environmental conditions.
Field identification & locations
Identified by its visible sand-sized grains and gritty texture; widely found in deserts, riverbeds, and mountainous regions worldwide.
