caption_attribution_description: Verdite (fuchsite metamorphite) (6.5 cm across at its base) from the Precambrian of South Africa. Verdite is a ~monomineralic, microcrystalline fuchsite metamorphic rock to an impure, microcrystalline fuchsite metamorphic rock. The dominant mineral, fuchsite, is a greenish, chromium-rich muscovite mica. This rock was not accompanied by specific information, but it does come from the Archean of South Africa. It most likely comes from one of the two following South African verdite localities: 1) verdite lens in layered mafic-ultramafic dikes in shear zones in the Jamestown Schist Belt-Nelspruit Batholith transition area (the Nelspruit Batholith is Mesoarchean in age, 3.015 Ga); north or northwest of the town of Barberton, South Africa. 2) verdite lens or pod in ultramafic host rocks in the Onverwacht Group, Barberton Greenstone Belt, Paleoarchean, 3.30-3.55 Ga; southwest of the town of Barberton, South Africa.
context_page_description: Fuchsite, also known as chrome mica, is a chromium rich variety of the mineral muscovite, belonging to the mica group of phyllosilicate minerals, with the following formula: K(Al, Cr)₂(OH)₂.
  Trivalent chromium replaces one of the aluminium atoms in the general muscovite formula producing the apple green hue distinctive of fuchsite. It is often found in minute micaceous aggregates, as a major component of chromium rich phyllitic or schistose metamorphic rocks of the greenschist facies.
  Verdite is a type of metamorphic rock made mostly of an impure, often multicolored, variety of fuchsite. It is used for ornamental carvings.
  Fuchsite is named after the German chemist and mineralogist Johann Nepomuk von Fuchs.
