Sandstone
Sedimentary Rock (Quartz arenite / Lithic sandstone)
Hardness varies from 6 to 7 depending on cement; color ranges from brown, tan, yellow, red, to grey; dull or earthy luster; clastic texture with visible or microscopic sand-sized grains; poor to moderate cleavage.

Physical properties
Hardness varies from 6 to 7 depending on cement; color ranges from brown, tan, yellow, red, to grey; dull or earthy luster; clastic texture with visible or microscopic sand-sized grains; poor to moderate cleavage.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles or rock fragments, principally quartz and feldspar, in environments such as deserts, rivers, and beaches over millions of years.
Uses & applications
Widely used in construction as a building material, for paving, landscaping, and in the manufacture of glass and abrasives.
Geological facts
Sandstone forms many of the world's most famous geological landmarks and monuments due to its durability and resistance to weathering, such as Zion National Park and Petra.
Field identification & locations
Easily identified by its gritty texture, visible sand grains, and layered bedding structures. Common worldwide in sedimentary basins and arid or coastal regions.
