Geoelectrical anomalies and diamonds in the Ukrainian Shield
Bibliographic record
Abstract
Regions of anomalously low magnitudes of electric resistivity were found and geoelectric models of the Earth crust and upper mantle of Ukraine were built. Ukrainian Shield (USh) is rich by anomalous objects of high electrical conductivity in the Earth crust and upper mantle. Geoelectrical parameters are also observed to be considerably non-uniform in the USh mantle. In the southwestern part of USh was found a conductor with the upper layer at 50-70 km with =25 ‐ 30 Om-m. In the west the conductor reaches the depth of 90-100 km and is galvanically linked with the anomaly in the upper mantle of the Carpathian region. This deep mantle anomaly could be considered analogous to the Slave province of Canada. All kimberlite pipes that have been found in the Ukraine correlate with the anomaly of conductivity of the Earth crust: with Priazovian, Kirovogradian and Volynian. In Podolian megablock area the kimberlites has not been found, but the presence of their indicating minerals are rather common. The pyropes were formed in the wide range of the pressure conditions. In the region of the mantle’s anomalies the mantle is poorly depleted and is metasomaticly changed and consists from eclogites and similar rocks, whose melting temperature is lower than the melting temperature of the surrounding mantle rocks. From the seismic data it is possible to assume the existence of the powerful lithosphere. Above the “diamond-graphite” stability level, the carbon could exist in the form of the high conductivity graphite, when below that level the carbon crystallizes into the diamond with the high electrical resistivity. Ancient lithosphere of the upper mantle was characterized by the low values of oxygen volatility. For this oxidation-restoration state of the depth matter corresponds the existence of carbon saturated fluids with the high concentration of hydrocarbons.

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.
