Uvarovite most commonly occurs in
solid solution with
grossular or
andradite, and is generally found associated with
serpentinite,
chromite, metamorphic limestones, and
skarn ore-bodies. The uvarovite crystals found in the Outokumpu district are among a wide range of chromium-rich silicate phases found in association with
volcanogenic copper-cobalt-zinc sulfide ore deposits which are known to have an unusually high chromium content. Uvarovite occurrences in the United States are predominantly found in the western portion of the country, including localities in
New Mexico,
Arizona, and
California. In the eastern United States, uvarovite has been confirmed in
Lancaster County,
Pennsylvania. 9 grains of uvarovite occur in a heavy mineral fraction of bulk stream sediment HM-10 collected in Bunker Hill creek, below the historic Bunker Hill gold mine, south of Nelson in British Columbia Canada. Its source is likely near serpentinites and argillaceous limestones within about 450 m upstream of the silt site. Notable localities in Europe besides the Outokumpu site known to bear uvarovite include
Røros, Norway;
Pitkyaranta, Russia;
Val Malenco, Italy; Pico do Posets near
Venasque, Spain;
Kip Daglari, Turkey; and
Biserk and
Sarany, Russia. and from the Vumba Schist Belt in
Botswana. In Asia, uvarovite has been reported from
Taiwan and
Japan. In
Australia, uvarovite has been reported from chromite deposits in southern
New South Wales. ==Properties==
