Résumé	(disponible en anglais seulement) This report of U-Pb zircon isotopic data accompanies the geological synthesis of the region of the Pipmuacan Reservoir (NTS 22E) by Hébert et al. (in press). The geological synthesis of this region, dominated by plutons and orthogneisses, uses precise ages to outline an igneous geochronological framework for the region, which is extended to the Grenville Province of Quebec. Ages reported in the synthesis were either previously published or are new and documented here. Geochronology samples for this report were selected by Dr. Claude Hébert to constrain age relationships underpinning geological mapping in the Pipmuacan Reservoir region. Contextual map locations are shown in the geological synthesis. For each sample, this technical report 1) describes analytical techniques and data reduction procedures used, citing references with further information, 2) presents tables of U-Pb isotopic data that also give UTM coordinates, 3) displays isotopic ratios and uncertainties in concordia diagrams 4) interprets these data and 5) assigns U-Pb zircon ages with analytical uncertainties. Technical information is thereby made available for reassessment in case of questions concerning conflicting radiometric ages or geological relationships.
