U-Pb zircon geochronology constraints on timing of plutonism and sedimentary provenance from the Clearwater Fiord-Sylvia Grinnell Lake area, southern Baffin Island, Nunavut [electronic resource] / N.M. Rayner. [Ottawa] : Natural Resources Canada, c2017. 30 p. : charts (some col.), col. maps, photos. (some col.) Open file ; 8204 Includes bibliographical references. "This report presents a compilation of Sensitive High Resolution Ion Microprobe (SHRIMP) U-Pb geochronological results from 11 samples (nine metaplutonic and two metasedimentary rocks) from southern Baffin Island. The analytical work presented here utilizes samples collected during geological mapping of the Clearwater Fiord-Sylvia Grinnell Lake area in the summer of 2015. Field and analytical work was carried out as part of Natural Resources Canada’s Geomapping for Energy and Minerals (GEM2) Baffin program. This report consists of a brief summary of the U-Pb results, followed by separate sections for each sample containing location coordinates, lithological and zircon descriptions, detailed presentation of the geochronological results, and preferred interpretation”--Intro., p. 1. gccst Geochronology gccst Structural geology Canada.
