Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation; colors include brown, tan, yellow, and red; dull luster; granular texture.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, chiefly quartz and feldspar, in marine, lake, or desert environments.
Uses & applications
Widely used in construction as a building material, for paving stones, and in the manufacturing of glass.
Geological facts
Sandstone formations can be very porous, making them excellent aquifers for storing groundwater and natural gas.
Field identification & locations
Identified by its visible sand grains and gritty texture; commonly found in ancient riverbeds, deserts, and coastal regions worldwide.
