Physical properties
Hardness: 6-7 (Quartz grains); Color: Tan/Grey; Luster: Dull/Earthy; Structure: Clastic; Cleavage: None; SG: 2.2-2.8.
Formation & geological history
Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments over millions of years in marine or terrestrial environments.
Uses & applications
Used in construction, as a decorative stone, and as a reservoir rock for groundwater and petroleum.
Geological facts
Sandstone represents about 20-25% of all sedimentary rocks. The Grand Canyon's layers are famous examples of sandstone stratigraphy.
Field identification & locations
Identify by its gritty texture (feels like sandpaper) and visible sand grains. Found globally in basins and coastal regions.
