Physical properties
Hardness of 6-7 on Mohs scale, tan to brown color, dull or earthy luster, granular texture, and specific gravity around 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years in desert, river, or marine environments.
Uses & applications
Widely used in construction as building stone, dimension stone, paving material, and in the manufacturing of glass and concrete.
Geological facts
Sandstone often preserves ancient ripples and fossil tracks, offering a window into prehistoric environments and climates.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains; commonly found in sedimentary basins and escarpments worldwide.
