Physical properties
Hardness of 6-7 on Mohs scale depending on cement, typically tan, brown, or red, dull to earthy luster, and composed mostly of quartz grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz and feldspar, over millions of years.
Uses & applications
Commonly used in construction as building stone, paving material, and in the manufacturing of glass.
Geological facts
Sandstone layers can store vast amounts of groundwater and petroleum, making them crucial reservoirs for natural resources.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, found worldwide in deserts, riverbeds, and ancient marine environments.
