Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Amazonitic pegmatites of late Paleozoic age associated with the alkalinegranite formation are known in Russia in the Ural and in Tuva, as well as in Madagascar and in the USA. Characteristic for these are platy and lentiform forms of bodies, short length (as a rule, of several dozen meters) and thickness (up to 5 or 10 m).
