Physical properties
Hardness 6-7 on Mohs scale, predominantly tan to yellow-brown color due to iron oxide staining, dull to earthy luster, clastic texture with visible sand grains, no cleavage.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, in desert, river, or marine environments over millions of years.
Uses & applications
Widely used as a dimensional building stone, for architectural facades, paving stones, and in the manufacturing of glass and abrasive products.
Geological facts
Sandstone formations often preserve ancient ripple marks and dinosaur footprints, providing crucial data for paleoclimatic and paleontological studies.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible quartz grains; commonly found in sedimentary basins and escarpments worldwide.
