Physical properties
Hardness of 6-7 on the Mohs scale, predominantly pinkish-red to brown color, dull or earthy luster, granular texture, composed mostly of quartz grains cemented together.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, beach, or river environments over millions of years.
Uses & applications
Commonly used in construction as a building and paving material, decorative stone, and historically for grinding stones.
Geological facts
Sandstone often preserves ripple marks and fossils from ancient environments, making it valuable for geological studies of Earth's history.
Field identification & locations
Identified by its gritty texture and visible sand grains. Found worldwide in sedimentary basins, cliffs, and desert regions.
