MADUREZ TERMICA DE LAS SECUENCIAS CENOZOICAS DEL SUR DE CHILE
Bibliographic record
Abstract
The lower (Oligo-Miocene) continental section of the Cenozoic sequence in the South of Chile (Regions IX and X) carries coal seams, while the upper marine (Mid Miocene) has potential for hydrocarbon generation. Due to the potential economic importance of the Cenozoic strata, the thermal maturity has been investigated by comparison of inorganic (clays, zeolites) and organic (vitrinite reflectance) diagenetic indicators. The diagenetic level of the clays, zeolites and organic matter in samples from drill holes in the Temuco, Valdivia and Osomo provinces indicate that both the lower continental and upper marine sequences are immature. The catagenesis zone has not been reached in any of the drill holes sampled. lt seems improbable that any significant quantity of crude has been generated and only sub-bituminous quality coal is expected. The block-controlled post-Miocene tectonic framework, that defines the actual morphostructural landscape, makes areas with thicker overbunden (i.e. central Valley) a more prospective ground for studies. There deeper burying may have produced higher thermal maturity; therefore favoring hydrocarbon generation and increasing the coal maturity. KEY WORDS. Cenozoic rocks. Diagenesis. Coal seams. Southern Chile.

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.
