Résumé(disponible en anglais seulement)
The following report presents a compilation of geochemical and isotopic data collected in the course of a numbers of projects starting in 1981 with geological mapping and geochemical sampling of the Silurian Topsail igneous suite (TIS) (Whalen and Currie, 1988; Whalen et al., 1987a,b,c). A Canada-Newfoundland Cooperation Agreement (CNCA) (1990-1994) funded project focused mainly on Ordovician plutonism within the Notre Dame subzone (Fig. 1) (Whalen et al., 1997b) but included isotopic work on the TIS (Whalen et al., 1996). During the Red Indian Line Project, which was funded under the auspices of the 2000 to 2003 Targeted Geoscience Initiative (TGI), more extensive work was carried out within the southern Notre Dame subzone and the northern Dashwoods subzone (Whalen et al., 2006; van Staal et al., 2007, 2008). With funding from the 2005-2010 Targeted Geoscience Initiative 3 Program (TGI3) some further geochemical and isotopic work was carried out in the Buchans-Robert's Arm belt and the Burlington Peninsula, the results of which are included in this report.
The geochemical data presented herein should provide significant assistance in the regional correlation of units, as well as for constraining their tectonic setting and igneous petrogenesis. It complements previously released geochemical databases for central Newfoundland (e.g., Davenport et al., 1996; Jenner, 2002; Rogers, 2004; Zagorevski and Rogers, 2011).
