Geochemical comparison of mafic, felsic, and ultramafic rocks in the Hurricane Mountain mélange to the Boil Mountain ophiolite complex, west-central Maine
Bibliographic record
Abstract
The Hurricane Mountain mélange, Maine, marks the suture zone between the suspected Boundary Mountain and Gander terranes. To the west the Hurricane Mountain mélange is bounded by the Boil Mountain ophiolite complex, and on the southeast it is overlain by the Dead River flysch. This ophiolite- mélange -flysch sequence may mark a terrane suture that trends northeast from the northern New Hampshire border across west-central Maine and into New Brunswick.
 
 The matrix of the Hurricane Mountain mélange includes mafic volcanic, felsic volcanic, metasedimentary and serpentinitc blocks Major and trace element analysis of the igneous blocks in mélange shows strong geochemical similarities to mafic volcanic, felsic volcanic and ultramafic units of the Boil Mountain ophiolite complex. Analysis of relict clinopyroxene grains further supports a correlation between the mafic mélange blocks and the upper mafic unit of the Boil Mountain ophiolite complex. Overall, the field, petrographic, and geochemical data suggest that the Boil Mountain ophiolite complex is the probable source for the exotic blocks in the Hurricane Mountain mélange.
 
 RÉSUMÉ
 Le mélange du mont Hurricane, au Maine, marque la zone de suture entre les terranes présumés du mont Boundary et de Gander. À l'ouest. Ic mélange du mont Hurricane est limité par le cortège ophiolitique du mont Boil, et à partir du sud-ouest, il est rccouvert par le flysch de la rivière Dead Ce cortège ophiolite-mélange-flysch pourrait marquer un terrane de suture orienté vers le nord-csi à partir de la frontière septentrionale du New Hampshire et traversant le centre-ouest du Maine jusqu'a 1'interieurdu Nouveau-Brunswick
 
 Les blocs a l'interieur de la matricc du mélange du mont Hurricane comprennent des roches volcanomafiques, des roches volcanofelsiques. des blocs métasedimentaires et des serpentinites. Les analyses des elements majeure et des éléments traces des blocs du mélange révèlent des similarités géochimiques marquees avec les unites volcanomafiques, volcanofelsiques et ultramafiques du cortege ophiolithique du mont Boil. Une analyse de grains de clinopyroxene résiduels appuie elle aussi une corrélation entre les blocs du mélange mafique et l'unité mafique supérieure du cortége ophiolitique du mont Boil. En somme les données de terrain et les données pétrographiques et géochimiques laissent supposer que le cortège ophiolitique du mont Boil constitue la source probable des blocs du mélange exotique du mont Hurricane

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.
