Physical properties
Hardness of 6-7 on Mohs scale, typically brown, tan, or reddish, dull to vitreous luster, clastic texture with visible quartz grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in various environments like deserts, rivers, and beaches.
Uses & applications
Widely used in construction as building stone, paving material, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone often preserves ancient ripple marks and fossil tracks, offering a window into prehistoric environments and climates.
Field identification & locations
Identified by its gritty texture and visible sand grains; commonly found globally in sedimentary basins and eroded cliffs.
