Physical properties
Hardness varies (typically 6-7 if quartz-rich), pale tan to light brown color, dull luster, clastic texture (sand-sized grains), grainy feel.
Formation & geological history
Formed by the compaction and cementation of sand grains, typically in ancient desert, river, or beach environments.
Uses & applications
Used in construction, as a building material, and for paving. Historically used for sharpening tools (whetstones).
Geological facts
Sandstone can serve as an important reservoir rock for groundwater, oil, and natural gas due to its porosity.
Field identification & locations
Identified by its sandy, granular texture that feels like sandpaper. Grains can often be seen with the naked eye. Found worldwide in sedimentary basins.
