Physical properties
Hardness: 6-7 (Mohs); Color: Tan to yellowish-brown with dark inclusions; Luster: Dull/Earthy; Structure: Granular/Clastic; Cleavage: None; Specific Gravity: ~2.6-2.8
Formation & geological history
Formed through the lithification of sand-sized minerals and rock grains, likely enriched with iron or manganese oxides during weathering and secondary mineralization (gossanization). Found in sedimentary basins.
Uses & applications
Primarily of geological interest; sometimes used as construction aggregate or as an indicator of underlying mineral deposits (sulfide ores).
Geological facts
While the user suggests this is a meteorite ('شهاب سنه'), the visual evidence lacks a fusion crust, regmaglypts, or metallic luster typical of meteorites; it instead shows a sedimentary grain structure and localized mineral nodules common to terrestrial weathered rocks.
Field identification & locations
Identify by granular sandpaper-like texture and lack of magnetic attraction. Common in the sedimentary Zagros fold-and-thrust belt of Iran. Collectors should check for high density or magnetic response to rule out meteoritic origin.
