Geology, Tebesjuak Lake, Nunavut
Bibliographic record
Abstract
The map area is underpinned by three Archean terranes from west to southeast: the Snow Island Suite of 2.6 Ga granite-rhyolite (AS), the Marjorie Hills assemblage of metasedimentary and granitoid gneiss (AMH), and orthogneiss of the Chesterfield block (unit Agn). The AS-AMH boundary is the Wharton Lake fault system, initially a southwest-dipping detachment. The AMH-Agn boundary is the dextral extensional Tulemalu Fault. Brittle reactivations of these faults localized sub-basins of the Baker Lake Group and hosted coeval intrusions of Martell Syenite (minette / ~1.83 Ga Hudson Granite mix). A Hudson Granite plug intrudes the AMH. Early gabbro/anorthosite (~1.77 Ga) of the Kivalliq igneous suite was intruded by Nueltin granite, co-magmatic with bimodal Pitz Formation lavas and the ~1.75 Ga, 015° McRae Lake diabase dyke swarm and compositionally related 075° Thelon River dyke swarm. Cu-Pb veins and replacements formed near mafic centres and Au-Ag-bearing quartz veins near felsic centres.
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.
How this classification was reachedexpand
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.
