Finite Element Modeling of Fluid Flow in Peace River Arch of Western Canada Sedimentary Basin:Implications for Hydrothermal Dolomitization
Bibliographic record
Abstract
This study aims at numerically investigating thermohaline fluid flow and its controlling factors related to the Devonian-age hydrothermal dolomitization in the Peace River Arch (PRA) area, Western Canada Sedimentary Basin. Simulation results indicate that faults serve as important conduits for upwelling fluid flow, which may bring reactants and heat from depth into the shallower Wabamun aquifer for dolomitization. Higher salinity distribution at depth impedes the upwelling hydrothermal fluid flow. However, evaporative conditions at surface during active tectonic stage allow high saline fluids to move downwards into the aquifer but prevent hot fluids flowing into it from depth. Topography does not significantly influence the fluid flow patterns in the PRA. Therefore, buoyancy- and topography-induced fluid flow is likely not responsible for the hydrothermal dolomitization in the study area, and other driving mechanisms need to be investigated.

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.
