THE IMPORTANCE OF COOLING REGIME IN THE FORMATION OF MELT INCLUSIONS IN OLIVINE CRYSTALS IN HAPLOBASALTIC MELTS
Bibliographic record
Abstract
Experiments using synthetic mafic liquids of composition Fo30Di30An40 and Fo22Di58An20 (wt.%) were conducted to constrain the range of cooling regimes over which melt inclusions form in olivine crystals. In one set of experiments, batches of melt were cooled at rates of 1, 7, 10, 50, 100, and 250°C/h from superliquidus temperatures to 1350 or 1300°C, below the liquidus temperature (1450°C) of both bulk compositions. In a second set of experiments, samples were cooled at rates of 100°C/h and 250°C/h to temperatures of 1300, 1350, or 1400°C, where they were held isothermally for six hours before quenching. Melt inclusions form at cooling rates between 7°C/h and 250°C/h in experiments with no isothermal period. More abundant inclusions formed in the second set of experiments, with an isothermal period. In some cases, melt inclusions form by the simultaneous growth or oriented agglomeration of neighboring platy crystals. This mechanism is consistent with observations of linear trends of inclusions and re-entrants, as well as the composite appearance of platy crystals and long narrow re-entrants between plates.

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.
