Abstract

fetched live from OpenAlex

The Atlantis-Meteor Seamount Complex, a group of submarine volcanoes located about 700 km to the south of the Azores, was investigated on the basis of seismic, magnetic and gravity data. The depths in the area around the seamount complex are too shallow compared to the standard cooling curve for oceanic lithosphere. The free air anomalies in the area are predominantly positive. Thermal lithospheric rejuvenation caused by the injection of heat into the lithosphere, embodied by intrusive masses, has been proposed as a unifying concept. A flexural study was carried out and resulted in estimates of the elastic thickness of the lithosphere under the various seamounts. Assuming that these values represent the lithospheric thicknesses under the seamounts at the time of loading, the ages of the seamounts are found to range from 38 to 66 Ma. This is in conflict with the Early Miocene to Late Oligocene age of the seamount complex inferred from a sediment model-study, a subsidence analysis, and two available K-Ar determinations. It is argued that the excessive ages found in the flexural study are due to the neglecting of the effect of thermal lithospheric rejuvenation on the elastic thickness of the lithosphere (lithospheric thinning). Lithospheric thinning will become evident as a decrease of the flexural rigidity and, therefore, means a resetting of the age of the lithoshere when loaded. As a result, the computed ages of the seamounts become too large. It appears that the degree of lithospheric thinning under the seamounts of the Atlantis Meteor Seamount complex is by no means uniform.

Full frame distilled prediction

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.
