Modelaje Geoquímico de la Manifestación Volcanico-Exhalativa Submarina “Los Tramojos” en el Complejo Vulcanógeno Sedimentario de Cuba Central.
Bibliographic record
Abstract
We studied an outcrop of massive iron-copper-zinc sulphides in Cretaceous volcanogenic intermediate to felsic rocks, located to the south of the village Los Tramojos, in the province of Sancti Spiritus, in Central Cuba. It is an artificial cut of dacitic tuffs and volcanic breccias with a strong mineralized area, dark in color, containing pyrite, magnetite, barite, sphalerite, bornite and others copper sulphides, as well as apatite, galenita and chalcopyrite. This area includes another tectonic zone with limonitic, hematitic, zeolitic and chloritic alterations, in contact with tuffs and non-mineralized and fresh volcanic breccias. It is a manifestation of a submarine volcanic-exhalative type. The mineralized area described above are very like the so call "Black Ores" of the Kuroko type of deposits. We investigated an area of 3,000 m2 using a soil grid of 25 x 10 meters, with some lithogeochemical samples. This study allowed to determine the correlation coefficients characteristic of the ore zone. We recommend the use of these correlation coefficients, combined with geophysical and perforation work, to check ore potential of the Sector "Los Tramojos".

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.
