Preliminary results of field mapping, petrography, and GIS spatial analysis of the West Tuya lava field, northwestern British Columbia
Bibliographic record
Abstract
An overview and summary of fieldwork, GIS spatial analysis, and preliminary petrographic analysis conducted between July 2003 and August 2004 is presented for the West Tuya lava field, which is part of the northern Cordilleran volcanic province, in the south-central part of the Jennings River (NTS 104-O) map area, northwestern British Columbia. The most important preliminary results include the following: a) identification of three subaerial shield volcanoes, which, based on mineralogy, probably range in composition from alkaline basalt to nephelinite and/or mafic phonolite, b) confirmation that mantle-derived peridotite inclusions ranging from 1 to 4 cm in size are present at two of the volcanoes, and c) interpretation of the subaerial lava flows as predating the Holocene. Using the 3D Analyst extension of ArcGIS 8.3, the minimum and maximum volumes of material erupted can be constrained to 10.36 km3 and 23.42 km3, respectively.
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.
