| Abstract | This new map of the Precambrian geology of Boothia Peninsula, Nunavut, is a key tool to strengthen the geoscience knowledge base of north-central Nunavut, and presents a significant update to knowledge
acquired in 1962 (Blackadar,1967) and 1986-1990 (Frisch, 2011). Through modern-concept bedrock mapping in 2017 and 2018 and supported by high-resolution geophysical and geochronological data sets, this map portrays in colours the location of at least
18 different crustal components that are distinguished on the basis of composition, mineral assemblage, and/or age. Several generations of folds and fabrics are portrayed (line types), with zones of more intense and localized high strain (shear
zones) also shown (red). The new knowledge highlights a complex polydeformed terrane that is distinct from rocks to the south and southeast, and shows that mineral exploration strategies for other parts of Nunavut may not be transferable to the
Boothia Peninsula - Somerset Island region. |

This new map of the Precambrian geology of Boothia Peninsula, Nunavut, is a key tool to strengthen the geoscience knowledge base of north-central
Nunavut, and presents a significant update to knowledge acquired in 1962 (Blackadar,1967) and 1986-1990 (Frisch, 2011). Through modern-concept bedrock mapping in 2017 and 2018 and supported by high-resolution geophysical and geochronological data
sets, this map portrays in colours the location of at least 18 different crustal components that are distinguished on the basis of composition, mineral assemblage, and/or age. Several generations of folds and fabrics are portrayed (line types), with
zones of more intense and localized high strain (shear zones) also shown (red). The new knowledge highlights a complex polydeformed terrane that is distinct from rocks to the south and southeast, and shows that mineral exploration strategies for
other parts of Nunavut may not be transferable to the Boothia Peninsula - Somerset Island region. |
