Physical properties
Hardness of 6-7 on Mohs scale depending on cement, colors range from tan to red, dull luster, quartz-rich composition with prominent grain texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in marine, desert, or river environments over millions of years.
Uses & applications
Widely used in construction as a building material, dimension stone, paving, and in the manufacture of glass and abrasives.
Geological facts
Sandstone formations often preserve ancient ripple marks and cross-bedding, providing geologists with vital clues about past climates and environments.
Field identification & locations
Identify in the field by its visible sand-sized grains and gritty texture; commonly found in deserts, riverbeds, and mountainous sedimentary layers worldwide.
