Physical properties
Hardness of 6-7 on the Mohs scale, tan to reddish-brown color, dull to earthy luster, clastic texture with visible sand grains, specific gravity of 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in desert, river, or marine environments over millions of years.
Uses & applications
Widely used in construction as a building and paving material, dimension stone, and historically for grindstones.
Geological facts
Famous structures like Petra and the US White House are built from sandstone. It frequently preserves ancient ripples and fossil tracks.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains; found worldwide in sedimentary basins.
