Physical properties
Hardness: 6 to 7 on the Mohs scale, Color: Brown/Tan, Luster: Dull or earthy, Crystal structure: Clastic (composed of cemented mineral particles or rock fragments), Cleavage: None, Specific gravity: 2.2 to 2.8
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in various environments such as deserts, rivers, and beaches over millions of years.
Uses & applications
Used in construction as a building material, dimension stone, paving, and sometimes in the manufacture of glass and abrasives.
Geological facts
Sandstone often preserves ripple marks and cross-bedding from ancient water currents or windblown dunes, providing geologists with a record of past environments.
Field identification & locations
Commonly found in sedimentary basins worldwide. Field identification relies on its gritty texture (feeling like fine sandpaper) and visible grains.
