GEOCHEMISTRY OF OPHIOLITIC BASALTS FROM THE METCHOSIN IGNEOUS COMPLEX ON SOUTHERN VANCOUVER ISLAND, AND THEIR INFERRED PALEOTECTONIC SETTING
Bibliographic record
Abstract
Major and trace elements geochemistry of Early Eocene rocks from the Metchosin Igneous Complex, a partial ophiolite located on Vancouver Island provide insight on its paleotectonic origin. Major and trace elements composition of volcanic rocks from the Metchosin Igneous complex indicate that they have compositions akin to MORB. These volcanic rocks extend from N-MORB to E-MORB compositions in various trace elements tectonic discriminant diagrams, and therefore support the hypothesis that the Southern Vancouver Ophiolite formed in a transitional tectonic setting, likely a divergent plate margin located near a continent. Mantle normalized trace element patterns of basalts from the Metchosin Igneous Complex are similar to those of the Gulf of California. A plausible modern analogue is therefore the Gulf of California of the Red Sea where a mid-ocean ridge developed into a continental rift.

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.
