AbstractNortheastern 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.
Summary(Plain Language Summary, not published)
This is a bedrock geological map at 1:50,000 scale of the north eastern part of Baie Verte Peninsula, Newfoundland (NL). The map is based on new (TGI-3 2006-2008) and compiled scientific information. Baie Verte Peninsula has hosted a dozen past producing mines (gold, copper, asbestos) and two are currently in production (adjoining map sheet). New bedrock mapping and age determinations of volcanic rocks allow the authors to establish correlations between ancient seafloor deposits that host copper and gold mineralization on the eastern coast of Baie Verte Peninsula, with similar rocks in the interior of the peninsula that host the Rambler mining camp. These correlations provide a predictive framework to guide future mineral exploration in the Baie Verte area. New mapping, age determinations and aeromagnetic data arising from this project, also reveal the complex folding and stratigraphy of younger continental volcanic sequences in the eastern half of the peninsula that locally host gold mineralization.
