Abstract

fetched live from OpenAlex

Environmental geochemistry is concerned with the abundance, distribution, and mobility of elements at the Earth's surface. It is important for land use management and health protection because Earth surface geochemistry affects life. Through regional surveys and detailed studies, the Geological Survey of Canada (GSC) provides the key geoscience basis for managing environmental issues. This work shows the natural distributions and concentrations of elements for much of Canada. It tells us about their bedrock origins, mineral hosts, and chemical forms, and the dispersal processes associated with their distribution in the landscape. Natural background variations shown by GSC maps can be used to identify areas of potential geochemical hazard and to distinguish between natural and industrial sources. This synthesis shows the application of geoscience research to environmental geochemistry.

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.

Not 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.
