The Magma Conduit System of Canada Voisey’s Bay Ni-Cu-Co Sulfide Deposit——Representative Example of Small Intrusions Mineralization

The Voisey's Bay Intrusion(VBI) is located in the Mesoproterozoic Nain Plutonic Suite (NPS) in Labrador,Canada.The Voisey's Bay deposit is hosted in a 1.34 Ga intrusion composed of troctolite,olivine gabbro,and ferrogabbro.The Voisey's Bay Intrusion consists broadly of two intrusions-the outcropping heavily mineralized Eastern Deeps Intrusion and the buried Western Deeps Intrusion.These intrusions are possibly connected by a contemporaneous continuous variably mineralized dyke.There have many contemporaneous intrusions in the area of Voisey's Bay,Voisey's Bay Intrusion have the minimum volume and just the VBI developed in to a large-scaleNi-Cu-Co sulfide deposit,it is the representative example of small intrusions mineralization.
