Abstract

fetched live from OpenAlex

Abstract Quartz veins at the Mufferaw gold prospect and Komis gold deposit, northern Saskatchewan, are examples of oblique-extension veins that crystallized in shear and tensile fractures, which propagated and then opened oblique to their walls during a single continuous deformation event. The Mufferaw gold prospect consists of an interlinked mesh of conjugate shear fractures, tensile fractures, and veins. Oblique-extension veins crystallized in conjugate shear fractures, which opened during dilation of intersecting tensile fractures under the same far-field stress system. At the Komis gold mine, tensile and dextral shear fractures cut across granodiorite dikes. The tensile fractures formed perpendicular to the dike margins during stress transfer from the less-competent country rocks to the more-competent dikes. During extension of the dikes oblique to the bulk extension direction in the country rocks, the tensile fractures were reactivated as sinistral shear fractures. The reactivated tensile fractures and dextral shear fractures opened oblique to their walls, parallel to the bulk extension direction, and were sealed by the deposition of oblique-extension veins during the same deformation event.

Teacher imitation

Not 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.
