VOISEYÕS BAY NICKEL ORE
HereÕs a nice nickel ore sample from a significant
nickel deposit in Canada - the VoiseyÕs Bay Ni-Cu-Co Magmatic Sulfide Deposit
in Labrador. Economic mineralization at VoiseyÕs Bay is moderately
complex, but in general consists of massive sulfide bodies surrounded by &
sulfides disseminated in mafic intrusive igneous rocks (troctolites &
gabbros). The key economic mineral in this deposit is pentlandite
- a nickel iron sulfide. Other minerals are chalcopyrite,
pyrrhotite,
troilite, cubanite, and magnetite.
Unit & Age: VoiseyÕs Bay Ni-Cu-Co Magmatic Sulfide Deposit, Nain
Plutonic Suite, mid-Mesoproterozoic, 1.333 billion years.
Locality:
VoiseyÕs Bay Mine, between VoiseyÕs Bay & Anaktalak Bay, southwest of Nain,
eastern coastal Labrador, eastern Canada (~56¡ 19' 50" North, ~62¡ 05' 58"
West).
Nickel ore (~5.5 cm across) - gabbro with intercumulate metallic sulfides
(principally pyrrhotite, chalcopyrite, pentlandite) from the VoiseyÕs Bay
Ni-Cu-Co Magmatic Sulfide Deposit (mid-Mesoproterozoic, 1.333 b.y.) at VoiseyÕs
Bay Mine, Labrador, Canada.
