Physical properties
Hardness 6-7 on Mohs scale, color ranges from yellow, brown, red, to gray, dull to earthy luster, quartz and feldspar mineral grains.
Formation & geological history
Formed by the accumulation, compaction, and cementation of mineral particles or rock fragments, typically in desert, river, or beach environments over millions of years.
Uses & applications
Commonly used in construction as a building material, dimension stone, paving, and in the manufacturing of glass.
Geological facts
Sandstone often preserves ancient ripples and fossil tracks, making it valuable for geological studies of past environments.
Field identification & locations
Easily identified by its gritty, sandpaper-like texture and visible mineral grains; found worldwide in sedimentary basins and cliffs.
