Physical properties
Hardness: 7 (Mohs), Color: Tan, golden, orange; Luster: Vitreous/Earthy; Structure: Granular/Hexagonal grains; Gravity: 2.65
Formation & geological history
Formed through the mechanical and chemical weathering of igneous rocks like granite. Grains are transported by water or wind and deposited in coastal or desert environments.
Uses & applications
Used in concrete production, glass manufacturing, metal casting, sandblasting, and beach nourishment projects.
Geological facts
Sand is the most consumed natural resource in the world after water. Quartz is preferred for industrial sand due to its chemical inertness and resistance to weathering.
Field identification & locations
Identify by granular texture and grit; individual grains are translucent under magnification. Found globally in deserts, beaches, and riverbeds.
