Physical properties
Hardness varies from 6 to 7 depending on cement; color ranges from tan, brown, yellow to red; dull luster; granular texture.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, mostly quartz and feldspar, over millions of years.
Uses & applications
Widely used in construction as a building material, dimension stone, and paving material.
Geological facts
Sandstone is often found in desert environments, beaches, and riverbeds, and forms many prominent geological cliffs worldwide.
Field identification & locations
Identify by visible sand grains and gritty texture; common globally in sedimentary basins.
