Geochemical and isotopic (Nd, O, Pb and Sr) data from igneous rocks of the Notre Dame Subzone and adjacent tectonostratigraphic zones, western and central Newfoundland
Bibliographic record
Abstract
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).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
