Linnaeite

Linnaeite

Named for Carl von Linne (Carolus Linnaeus), who was a Swedish taxonomist, botanist, physician, geologist, and zoologist. Linnaeite is found with cobalt and nickel sulfides in hydrothermal veins and is somewhat common and widespread, found in localities in Sweden, Finland, Germany, the Czech Republic, the USA, the Democratic Republic of the Congo, Zambia, Zimbabwe, and Namibia, among many other minor occurrences.
