Physical properties
Hardness varies around 6 to 7 on the Mohs scale depending on cement, exhibits red to brown color due to iron oxide, dull luster, and granular crystal structure.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert or river environments over millions of years.
Uses & applications
Widely used as a construction and building material, paving stone, and in landscaping.
Geological facts
Red coloration is primarily caused by hematite or potassium feldspar acting as a natural cementing agent.
Field identification & locations
Easily identified by its gritty texture and visible sand grains; commonly found in sedimentary basins worldwide.
