AbstractNorthwestern Baie Verte Peninsula (Newfoundland and Labrador, NTS 12-H/16 and part of 12-I/2) is underlain by Mesoproterozoic basement of the East Pond Metamorphic Suite; Neoproterozoic to Ordovician Laurentian continental margin rocks of the Fleur de Lys Supergroup; Cambrian dismembered ophiolite including Pacquet, Point Rousse, and Advocate complexes; submarine Ordovician ophiolite cover of the Snooks Arm Group; and Ordovician-Silurian, continental plutonic rocks of the Burlington plutonic suite and overlying Silurian Micmac Lake Group; King's Point volcanic complex; and Cape St. John Group and related plutons. Ten mines have operated in this area (two current, eight past-producing). The ophiolitic rocks host Cu-Au volcanogenic massive-sulphide (Terra Nova, Rambler Main, Big Rambler Pond, East, Ming, and Ming West mines) and asbestos deposits (Advocate mine). The Snooks Arm Group hosts three gold deposits (Goldenville, Stog'er Tight, and Pine Cove mines). Four phases of regional deformation affected this area including D1, best documented in the Birchy Complex, is related to ophiolite obduction; D2, regional, penetrative deformation was accompanied by greenschist- to amphibolite-facies metamorphism; D3, related to folds, commonly asymmetric; and D4, related to recumbent folding in the northeast and extensional and dextral faults and reactivation of faults.
Summary(Plain Language Summary, not published)
This is a bedrock geological map at 1:50,000 scale of the north central 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 (this map sheet). Careful mapping in combination with geochronology and geochemistry reveal for the first time how stratigraphic sequences of ancient ocean floor volcanic rocks and attendant copper and gold mineralization, have been progressively deformed into tight folds westward across the peninsula. Ultimately these constitute a collage of fault-bound slivers along a major fault zone (Baie Verte-Brompton Line) that can be traced across Newfoundland to southern Quebec. This fault zone reworks the ancient continental margin¿accreted seafloor plate boundary in the northern Appalachians.
