AbstractThis study is part of the Canada-Nunavut Geoscience Office's Hall Peninsula Integrated Geoscience Program, a multiyear bedrock and surficial geology mapping program with associated thematic studies. Bedrock mapping in 2012 refined previously delineated packages (from oldest to youngest): the Hall Peninsula orthogneiss, the Lake Harbour Group and the Cumberland Batholith (St-Onge et al., 2006). Field observations summarized in this report will form the basis of the legend for new 1:250 000 scale maps of the peninsula. Thematic studies focusing on regional tectonics,metamorphism, structure, geochronology and igneous activity (volcanic and/or plutonic) associated with metasedimentary packages have been initiated by university and government partners involved in the project.
The discovery of ultramafic rocks within supracrustal packages points to possible new sources of carving stone for Nunavummiut, as well as potential for nickel - copper - platinum-group element (PGE) mineralization. The large area underlain by tonalite orthogneiss is prospective for diamond-bearing kimberlites, similar to those 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 volcanogenic massive sulphide (VMS) deposits associated with supracrustal packages.
