Physical properties
Hardness varies from 6 to 7 on the Mohs scale depending on cementation; colors include tan, brown, yellow, and red; dull luster; composed primarily of quartz and feldspar grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or marine environments over millions of years.
Uses & applications
Widely used as a construction material for building facades, paving stones, and historically for grindstones.
Geological facts
Sandstone formations often act as excellent aquifers and reservoirs for oil and natural gas due to their porous nature.
Field identification & locations
Easily identified by its gritty texture, visible sand-sized grains, and layered bedding structures found worldwide in sedimentary basins.
