Physical properties
Hardness varies from 6 to 7 depending on quartz content, color ranges from tan, brown, yellow, red, to grey, dull luster, granular texture, composed mostly of quartz and feldspar grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in environments such as deserts, rivers, and beaches over millions of years.
Uses & applications
Commonly used in construction as building stone, paving material, and in the manufacture of glass and abrasives.
Geological facts
Sandstone is porous and permeable, making it an excellent natural reservoir for groundwater, petroleum, and natural gas.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains. Found worldwide in sedimentary basins and ancient depositional environments.
