Reconnaissance surficial geology, Duggan Lake, Nunavut, NTS 76-H
Bibliographic record
Abstract
Preliminary surficial geology studies, based on aerial photograph interpretation and limited legacy data, were undertaken in the Duggan Lake map area to provide an improved understanding of distribution and nature of surficial sediments and regional glacial history. Much of the area is extensively covered by a variety of glacial deposits and landforms, though bedrock outcrops can be found throughout the region. Widespread till veneer, blanket and streamlined till are common in the central and eastern areas, whereas hummocky till occurs in the west. Till-dominated terrain is cut by northwest-southeast trending glaciofluvial corridors consisting of eskers, ice-contact sediments, outwash plains and terraces, and locally elongated zones of scoured bedrock. Small isolated glacial lakes were formed by ponding of meltwater. In the northwest, a discontinuous moraine complex, consisting of glaciofluvial sediments and ridged till segments, forms the western extremity of a major end moraine system referred to as the MacAlpine Moraine. Drumlinoids and striations record a regional northwestward ice flow during the last glaciation.
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.
