Physical properties
Hardness: 6-7 (Mohs), Color: Tan/Beige, Luster: Dull/Earthy, Grain size: 0.0625 mm to 2 mm, Texture: Gritty like sandpaper
Formation & geological history
Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments, typically in river beds, deserts, or marine environments over millions of years.
Uses & applications
Primarily used as a common building material, decorative stone, for grindstones, and in the production of glass.
Geological facts
Sandstone makes up about 10-20% of all sedimentary rocks on Earth. It is a major reservoir for water (aquifers) and oil/gas due to its porosity.
Field identification & locations
Identify by its gritty texture and visible sand grains. Commonly found in coastal areas, arid deserts, and sedimentary basins worldwide.
