Geochemical characterization of plutonic rocks and U-Pb ages of dykes, Boothia Peninsula-Somerset Island, Nunavut / M. Sanborn-Barrie and D. Regis.: M183-2/8972E-PDF

"The Boothia Peninsula - Somerset Island area is an under-explored frontier region of the western Churchill Province, Canadian Shield where, until recently, knowledge has stemmed from 1962 and 1986-1992 geological mapping, undertaken without benefit of aeromagnetic constraints and with only limited U-Pb geochronology. Geomapping for Energy and Minerals (GEM) built upon this historical foundation through modern-concept bedrock mapping supported by high-resolution geophysical and geochronological data sets. To date, reports of field findings, value-added assay data, new geological maps and journal papers are ensuring that relevant data and knowledge are accessible for this region. This report contains a broad overview of the geochemical character of the major rock units recognized as comprising fundamental crustal components of the Boothia-Somerset region, based on major, minor and trace-element data for select samples"--Introduction, page 2.
