Physical properties
Hardness of 6-7 on Mohs scale, typically brown or tan in color, dull or earthy luster, granular crystal structure with quartz grains.
Formation & geological history
Formed from the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, over millions of years.
Uses & applications
Commonly used in construction, as building stone, and for paving or flooring materials.
Geological facts
Sandstone often preserves ancient environments, showing ripple marks and cross-bedding from ancient rivers or deserts.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains, found worldwide in sedimentary basins.
