Physical properties
Hardness of 6 to 7 depending on cement, color ranges from tan, brown, yellow to red, dull luster, granular texture, specific gravity of 2.2 to 2.8.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, mainly quartz and feldspar, in environments like deserts, rivers, and beaches.
Uses & applications
Used extensively in construction as a building material, dimension stone, and in paving, as well as an aquifer for groundwater.
Geological facts
Sandstone formations like Zion National Park and Petra display spectacular cross-bedding formed by ancient wind or water currents.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible sand grains; widely distributed globally.
