Physical properties
Hardness 6-7 on Mohs scale, earthy luster, tan to brown color, granular texture, specific gravity 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or marine environments.
Uses & applications
Widely used in construction for building stone, paving, and making glass due to its high quartz content.
Geological facts
Sandstone often preserves ancient ripple marks and fossil tracks, providing vital clues about prehistoric environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains; found worldwide in sedimentary basins.
