Physical properties
Hardness of 6-7 on the Mohs scale depending on cementation; Color ranges from tan, brown, reddish-brown to gray; Luster is dull to earthy; Structure is clastic with rounded quartz grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments over millions of years.
Uses & applications
Used in construction, building materials, landscaping, and as decorative accent stones.
Geological facts
Sandstone is one of the most common sedimentary rocks on Earth and has been used as a building material since ancient times due to its workability.
