"Northeastern Baie Verte Peninsula (Newfoundland and Labrador, NTS 2-E/13, parts of NTS 12-I/4, 2-E/14, and 2-E/12) is underlain by the Neoproterozoic to Ordovician Ming’s Bight Group, Cambrian ophiolite of the Betts Cove Complex, submarine Ordovician ophiolite cover of the Snooks Arm Group, and a continental overlap assemblage including Ordovician-Silurian Burlington plutonic suite, Stocking Harbour intrusive suite, and the Silurian Confusion Bay plutonic suite and Cape St. John Group. Three mines have operated in this area including two Cu volcanogenic massive-sulphide deposits in the Betts Cove Complex (Tilt Cove and Betts Cove mines), and gold in iron-formation in the Snooks Arm Group (Nugget Pond mine). Four phases of regional deformation affected this area, including: D1 restricted to a northwest-directed reverse fault in the Betts Cove Complex related to ophiolite obduction; D2 regional, penetrative deformation accompanied by greenschist metamorphism; D3 related to open upright cross folds; and D4 in the north, related to recumbent folding coeval with extensional faults, accompanied by an amphibolitic metamorphic overprint"--Abstract.
