AbstractThis study is part of the Canada-Nunavut Geoscience Office's Hall Peninsula Integrated Geoscience Program, a multiyear bedrock and surficial geology mapping program with associated thematic studies.Modern geological maps not only record lithological observations but incorporate interpretations on the nature of the protolith and the subsequent metamorphic, deformation and tectonomagmatic history. Precise, absolute age constraints are an essential component of modern mapping, as they aid in the calibration of the legend, strengthen regional correlations and place time brackets on tectonometamorphic events. Acomprehensive uranium-lead geochronology research program is underway at the Geological Survey of Canada Geochronology Laboratory in support of new 1:250 000 scale geological maps of Hall Peninsula, Baffin Island, Nunavut.
