...B.M. Saumur; A.R. Cruden Abstract The Mesoproterozoic Voisey’s Bay intrusion is a small (∼10 km 3 ) mafic intrusive complex forming part of the 20,000 km 2 Nain plutonic suite of Labrador (Canada) and hosting a world-class orthomagmatic Ni-Cu sulfide ore deposit. An extensive database of drill-core...
