Physical properties
Hardness of 6 to 7 on the Mohs scale depending on cement, colors range from tan and brown to red and yellow, dull luster, quartz-dominated mineral grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in desert, river, or marine environments.
Uses & applications
Widely used in construction as a building stone, paving material, and in the manufacturing of glass and abrasives.
Geological facts
Sandstone often preserves ancient ripple marks and cross-bedding, offering direct clues about prehistoric environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, commonly found in desert regions and ancient riverbeds.
