Physical properties
Hardness of 6-7 on Mohs scale, typically tan to brown in color, dull or earthy luster, granular crystal structure, poor cleavage, specific gravity around 2.2-2.8.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, primarily quartz, over millions of years in marine, desert, or river environments.
Uses & applications
Widely used in construction for building stone, paving, and flagging, as well as in manufacturing glass and abrasives.
Geological facts
Sandstone formations often preserve ancient ripple marks and fossilized tracks, providing key clues about prehistoric environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains; commonly found in layered cliffs, deserts, and riverbeds worldwide.
