AbstractIn 2012, the Canada-Nunavut Geoscience Office initiated a targeted regional bedrock mapping project on Hall Peninsula, southern Baffin Island. During the first field season, mapping focussed on the southern portion of the peninsula covering approximately 20 000 km2. Mapping defined two lithological domains: an eastern domain comprising a tonalite gneissic basement overlain or imbricated with supracrustal rocks, and intruded by two granitic suites; and a western domain characterized by metasedimentary rocks intruded by a tonalite-granodiorite suite, charnockite and garnet monzogranite. The discovery of ultramafic rocks points to possibly interesting new sources of carving stone and may also have potential for nickel-copper-PGE mineralization. The large area underlain by orthogneiss basement units could be host to diamond-bearing kimberlites similar to the ones found in the northern portion of the peninsula. Based on the reported geology, other types of mineralization can also be considered, such as gold associated with iron-formation and VMS deposits associated with supracrustal packages.
Summary(Plain Language Summary, not published)
During the summer of 2012 the Canada-Nunavut Geoscience Office initiated a project to map the bedrock and surficial geology of the Hall Peninsula, southern Baffin Island. Work focussed on the southern portion of the peninsula covering approximately 20 000 km2. Two eastern and western geological domains characterized by different rock strata were recognized. The discovery of rocks originating deep in the Earth's mantle points to possibly interesting new sources of carving stone and may also have potential for nickel-copper-PGE mineralization. The eastern domain may be host to diamond-bearing kimberlites similar to those found in the northern portion of the peninsula. As well, the improved geological context for the peninsula allows consideration of other types of mineralization in this part of Baffin Island, such as gold associated with iron-formation and volcanic massive sulphide mineralization.
