Physical properties
Hardness of 6-7 on Mohs scale, reddish-brown color due to iron oxide, dull to earthy luster, clastic texture with visible sand grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert or river environments.
Uses & applications
Widely used in construction, paving, architectural facing, and as a decorative stone.
Geological facts
Red coloration is caused by hematite cement coating the quartz grains. It frequently displays cross-bedding from ancient wind or water currents.
Field identification & locations
Identify by its gritty texture and visible sand grains; commonly found in sedimentary basins worldwide.
