Physical properties
Hardness of 6-7 on Mohs scale, colors vary from tan and brown to red and grey, dull luster, composed mainly of quartz and feldspar grains.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments.
Uses & applications
Widely used in construction, building facades, paving, and as a raw material for glassmaking.
Geological facts
Sandstone formations can store vast amounts of groundwater and petroleum, making them crucial reservoir rocks.
Field identification & locations
Identified by its gritty, sandpaper-like texture and visible mineral grains; found worldwide in ancient and modern sedimentary basins.
