Abstract
Hydrothermal systems strongly contribute to planetary habitability and must be considered in the search for life in the universe. Studies of hydrothermal systems on Earth can provide insight into the role these systems play in dictating planetary habitability. Yet, because they are intimately connected to plate tectonics and the history of Earth's ocean–atmosphere system, most hydrothermal systems on Earth probably differ from those that feature on other rocky planetary bodies. We provide two comparative studies to show how hydrothermal processes in our modern oceans likely differ from their ancient analogues and those on prebiotic planetary surfaces. We first outline the role of elevated seawater sulfate in controlling the chemistry and style of modern high-temperature hydrothermal vents and discuss how oxygenation of the atmosphere and oceans has thus affected our view of seafloor hydrothermal systems. We then examine how the evolution of silicifying organisms yields different minerals and fluxes in serpentinizing systems on the modern ocean floor relative to their ancient counterparts. We conclude by outlining the potential for adapting existing geochemical tools to study the contributions of hydrothermal systems to the habitability of planetary bodies, including exoplanets.

Full frame distilled prediction
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
