| Abstract | 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 thick-skinned, 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. |
| Summary | (Plain Language Summary, not published)
The Hall Peninsula Integrated Geoscience Program was led by the Canada-Nunavut Geoscience Office, and was designed to increase geoscience knowledge and
assess the economic potential of the area. Eastern Hall Peninsula is mostly underlain by Archean tonalite to quartz-diorite orthogneiss, while Paleoproterozoic supracrustal and intrusive rocks are exposed to the west. The supracrustal rocks comprise
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 3 phases of deformation associated with the
Trans-Hudson Orogen that have produced thick-skinned, east-verging fold and thrust structures and amphibolite- to granulite-facies mineral assemblages. Hall Peninsula hosts a highly prospective kimberlite field, as well as mafic, ultramafic, and
carbonate rocks that may contain metal, semi-precious gemstone and carving stone resource potential. |
