Physical properties
Hardness of 6-7 on Mohs scale, typically tan to brown in color with a grainy texture and dull luster. Composed mainly of quartz and feldspar grains cemented together.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in marine, desert, or river environments.
Uses & applications
Widely used in construction as a building material, for paving, and in the manufacture of glass.
Geological facts
Sandstone often preserves ancient ripple marks and fossils, providing key clues about past geological environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, commonly found in sedimentary basins worldwide.
