Vishnevite is named for one of its co-type localities in the Vishnevy Mountains in Russia. The other type locality is in the Ilmen Mountains, also in Russia. Occurs “in poikilitic aegerine-nepheline-sodalite syenites and associated pegmatites” in few places including, additionally, Scotland, Sweden, Greenland, Tanzania, and in Colorado, USA.

Named for John Henry Vivian, the Welsh-Cornish mineralogist from Cornwall, England who discovered the mineral. Vivianite is a relatively common secondary mineral which occurs in oxidized metallic ore deposits and in granite pegmatites, as a replacement for organic material in fossilized bones, lake sediments, and in bog-iron ores and peat bogs, and as a rare mineral in caves. Some of the localities for Vivianite include in England, Germany, Serbia, Russia, Ukraine, Cameroon, the United States, Mexico, Brazil, Bolivia, and Japan.

Named for its discovery locality at the Vladimirovskoye deposit in Russia, Vladimirite also shares its type locality with the Khovu-Asky deposit, also in Russia. Found as a secondary mineral in arsenic-bearing deposits’ oxidized zones. Occurs in only a few localities worldwide including, additionally, Germany, Morocco, and in Michigan, USA.
