Abstract

fetched live from OpenAlex

The solar-like neon isotopic signature of the mantle suggests the presence of a primitive reservoir. Its origin remains a puzzle, though the literature suggests that a primordial H2 and He-rich atmosphere captured from the accretion disk was dissolved into a magma ocean. Our study investigates how much neon can be incorporated into the magma ocean based on the basal pressure of such an atmosphere and the neon solubility in mafic to ultramafic melts (49–34 wt. % SiO2 and 9–21 wt. % MgO). The neon solubility range obtained (3.4 × 10−4 to 6.5 × 10−5 cm3 STP g−1 bar−1) cannot match the primitive mantle theoretical neon content in a slow accretion scenario, demanding either fast accretion or alternative models for neon origin on Earth. Considering the planetary embryo mass required to accumulate enough neon (>0.8 times the mass of the Earth), the hypothesis of partial dissolution of the atmosphere into the magma ocean remains difficult to consider.

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.
