Physical properties
Hardness 6-7 on Mohs scale, reddish-brown color due to iron oxide cement, dull luster, clastic texture.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert or river environments.
Uses & applications
Used widely in construction as building stone, paving, and occasionally for decorative landscaping.
Geological facts
Red coloration often indicates the presence of hematite acting as a natural cement binding the quartz grains together.
Field identification & locations
Identified by visible sand grains and a gritty texture; commonly found in ancient desert deposits and riverbeds worldwide.
