Physical properties
Hardness of 6-7 on Mohs scale, tan to brown color, dull to vitreous luster, clastic texture composed mostly of quartz grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments.
Uses & applications
Commonly used in construction as building stone, paving material, and in the manufacturing of glass.
Geological facts
Sandstone formations can be millions of years old and frequently preserve ancient ripple marks and fossilized tracks.
Field identification & locations
Identify by visible sand-sized grains and a gritty texture; found worldwide in sedimentary basins and arid regions.
