Metal Concentrations and Metal Deposition in Deep Geothermal Wells at the Reykjanes High-temperature Area, Iceland
Bibliographic record
Abstract
Sulfide scale is precipitating at 2770 m depth and ∼330 °C in well RN-17B from unboiled, seawater-dominated hydrothermal fluids. The scale consists of well-crystallized pyrrhotite with minor sphalerite, and traces of galena, pyrite, and chalcopyrite. Gold concentrations in the bulk sulfides reach 40 ppm, and Ag concentrations reach 20 ppm. In another well, with similar fluid composition, sulfides scale formed due to boiling at 670 to 140 m depth (267 °C – 260 °C), and contains abundant skeletal sphalerite, minor chalcopyrite, trace of bornite, pyrrhotite, pyrite, and gold. Bulk concentrations of Au in this scale reach 100 ppm, and Ag concentrations range from 35 to 450 ppm.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
