Physical properties
Hardness: 6-7 (Mohs scale), Color: tan, grey, or greenish-brown, Luster: dull/earthy, Crystal structure: granular clastic texture, Cleavage: none, Specific gravity: 2.1-2.8
Formation & geological history
Formed through the accumulation and cementation of sand-sized mineral grains, mostly quartz and feldspar, in environments like rivers, deserts, or coastal areas over millions of years.
Uses & applications
Extensively used as a building material, masonry, road base, and in the manufacturing of glass and ceramics. Also popular for landscaping.
Geological facts
Sandstone is one of the most common sedimentary rocks in the Earth's crust; it often contains beautiful sedimentary structures like cross-bedding and ripple marks from ancient environments.
Field identification & locations
Identify by its gritty, abrasive feel similar to sandpaper and visible small grains. Found globally in canyon walls, plateaus, and outcrops near water sources.
