Abstract
Morphostructural features are essential for geothermal resource evaluation. They provide insights into geological structures and surface features that are linked to geothermal activity, thus enhancing exploration and resource characterization efficiency. This study assesses a place with recognized geothermal energy via structural lineaments, and morphological environments and geological units using diverse satellite images information and fieldwork resources to define the morphostructural framework of the Valle de Nereidas geothermal field. The results indicate that: 1) heat contribution in the study area is primarily associated with volcanic emission centers and units younger than 2 Ma, extending beyond the Nevado del Ruiz volcanic complex; and 2) fluid circulation and recharge zones correspond to fractured lava flows, where thermal contraction facilitates the infiltration and movement of regional groundwater. These findings suggest that the geothermal system in the Valle de Nereidas is controlled by both volcanic and structural features, where young volcanic edifices act as heat sources, and faulted and fractured zones enhance fluid circulation. Data from the drilled well Nereidas-1, including lithological descriptions, helped to establish relationships between subsurface geology and surface expressions of geothermal activity. These results help to define the spatial distribution of thermal anomalies and recharge areas, which directly impact resource sustainability and reservoir management. Furthermore, they provide valuable information for improving geothermal exploration strategies in the area by refining the model of subsurface heat transport and fluid dynamics.

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 it
