Abstract: An evaluation of awaruite in the Atlantic Lake area of the Pipestone Pond Complex, Newfoundland
Bibliographic record
Abstract
MICHAEL P. PILLER Department of Earth Sciences, Memorial University of Newfoundland, St. John’s, Newfoundland and Labrador A1C 5S7 Newfoundland hosts several well exposed ultramafic complexes that have been central to mineral exploration and mining activities for decades. These ultramafic bodies have undergone variable degrees of serpentinization: a low grade, retrograde metamorphic reaction in which minerals such as olivine and pyroxene break down to form one of the serpentine family of minerals and magnetite. Strongly reducing conditions caused by the release of H2 during the formation of magnetite provide conditions amenable to the formation of Ni-rich mineral phases such as awaruite (Ni3Fe). The nature of these Ni-bearing minerals is further defined by the available sulphur content of the system. Awaruite is formed under reduced conditions in the absence of sulphur and represents hydrous-metamorphic remobilization of nickel from its silicate residence in olivine. The scope of this project is i) to document awaruite and associated nickel mineralization in the Pipestone Pond Complex in central Newfoundland and ii) to constrain the geological conditions under which Ni-Fe alloy mineralization formed. Detailed mapping, core logging, polished petrographic thin sections, and the SEM-MLA will be utilized to investigate awaruite and associated minerals. The results of this research will be used to help guide exploration for Ni-Fe alloy minerals by identifying rock types which host the most significant awaruite, as well as provide some insight on the controls of mineralization.

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.
