The Hall Peninsula Integrated Geoscience Program was led by the Canada-Nunavut Geoscience Office, and was designed to increase the geoscience knowledge and assess the economic potential of the area. Eastern Hall Peninsula is dominantly underlain by Archean tonalite to quartz diorite orthogneiss, while Paleoproterozoic supracrustal and intrusive rocks are exposed to the west. The supracrustal rocks are dominated by pelitic, psammitic, amphibolite and calc-silicate units, are interpreted as correlative with the Lake Harbour Group, and are cut by granulite-grade monzogranite to diorite intrusions. Hall Peninsula records three phases of metamorphism and deformation associated with the Trans-Hudson Orogen that have produced thickskinned, east-verging fold and thrust structures and amphibolite to granulite facies mineral assemblages. Hall Peninsula hosts a highly prospective diamond kimberlite field, as well as mafic and carbonate supracrustal rocks, and ultramafic intrusions that may contain base and/or precious metal, semi-precious gemstone and carving stone resource potential.
