Physical properties
Hardness varies from 6 to 7 depending on cement; color ranges from tan, brown, yellow, to red; dull luster; granular texture composed mainly of quartz and feldspar.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, predominantly quartz, in marine, lake, or desert environments over millions of years.
Uses & applications
Widely used in construction as building stone, paving material, and for making glass due to its high silica content.
Geological facts
Sandstone formations like Zion National Park and Petra showcase spectacular wind and water erosion patterns formed over geological epochs.
Field identification & locations
Easily identified by its visible sand-sized grains and gritty texture; found worldwide in sedimentary basins and ancient riverbeds.
