Physical properties
Hardness of 6-7 on Mohs scale depending on cement, colors range from tan to red, dull to earthy luster, composed mainly of quartz and feldspar grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or marine 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 fossils, providing key clues about prehistoric environments and climates.
Field identification & locations
Easily identified in the field by its distinct gritty texture and visible sand grains; commonly found in layered sedimentary basins worldwide.
