Journal of Geological Research

The Qatruyeh iron deposits, located on the eastern border of the NW-SE trending Sanandaj-Sirjan metamorphic zone, southwest of Iran, are hosted by a late Proterozoic to early Paleozoic sequence dominated by metamorphosed carbonate rocks. The magnetite ores occurred as layered to massive bodies, with lesser amounts of disseminated magnetite and hematite-bearing veins.

Along with hematite, goethite is the other mineral that makes up most of the rust on natural and artificial iron exposures. As goethite's origins can be similar to those of hematite, the two minerals often occur together and may be confused for one another. However, the two can be distinguished by their streak.

Hematite Gemstone Information

Hematite is a gemstone form of iron oxide. It is the principal ore of iron and one of the few gemstones that exhibits a metallic luster. Like most other gemstones with a metallic luster, hematite is remarkably dense and possesses an extremely high refractive index. In fact, its specific gravity and refractive index is much higher than that of corundum, zircon and even diamond.
