U-Pb zircon geochronology of Archean greenstone belts (Mary River Group) and surrounding Archean to Paleoproterozoic rocks, northern Baffin Island, Nunavut / D.R. Skipton, N. Wodicka, V. McNicoll, B.M.... : M183-2/8585E-PDF
"Prior to 1:100,000-scale geological mapping conducted in 2017-2018, northern Baffin Island remained a major knowledge gap in the understanding of the northern Rae craton and the tectonic assembly of northeastern Laurentia. Geochronological data in the region was sparse; only four published U-Pb dates existed in the mapping area (~67,000 km²). Resolving the geology and age of the Archean Mary River Group – host to the Mary River iron mine – and the surrounding felsic-to-intermediate gneiss has key implications for the regional tectonic history and mineral prospectivity. In this study, we present new UPb zircon ages for 16 samples, including: 3 metavolcanic rocks and a quartzite from the Mary River Group; 2 psammite samples from newly discovered strata near Pond Inlet; 8 felsic-to-intermediate metaplutonic rocks; and 2 mafic metaplutonic rocks"--Abstract, page 1.
