AbstractSouthern Baie Verte Peninsula (Newfoundland and Labrador, NTS 12-H/9) is underlain by the Mesoproterozoic East Pond Metamorphic Suite, Neoproterozoic Birchy Complex, and Neoproterozoic to Ordovician Fleur de Lys Supergroup, which make up the Humber continental margin. East of the Baie Verte Line, the continental margin units are tectonically overlain by Cambrian rocks of the Advocate Complex (Baie Verte Oceanic Tract), and ophiolite cover of the Ordovician Snooks Arm Group and Black Brook group. These are stitched by a continental overlap assemblage including Ordovician-Silurian Burlington plutonic suite, and Silurian Micmac Lake Group, King's Point volcanic complex, and west of the Baie Verte Line, Wild Cove Pond Igneous Suite and late tectonic, Trap Pond granite. Four phases of regional deformation have affected this area including D1 best documented in the Birchy Complex and related to ophiolite obduction; D2 regional, penetrative deformation associated with isoclinal folds and shear zones and accompanied by greenschist- to amphibolite-facies metamorphism; D3 related to asymmetric and chevron folds near the Baie Verte Line; and D4 related to 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 south 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 (adjoining map sheet). New age determinations in this area establish a temporal link between contemporaneous volcanic rocks, and widespread, granitic intrusive rocks exposed on the eastern part of the peninsula. Evidence for tilted volcanic rocks and their plutonic roots, are important observations in helping to establish effective mineral exploration strategies for gold, silver and uranium mineralization associated with these rocks.
