Summary

This conference abstract reports measurements of stable potassium isotope compositions in mid-ocean ridge hydrothermal vent systems. The work contributes to understanding potassium cycling in modern oceanic environments and provides a baseline for interpreting ancient potassium isotope signatures in the geological record. As suggested by the title, the study carries implications for tracing potassium sources and sinks across geochemical reservoirs.

UK applicability

This fundamental geochemistry study has limited direct application to UK farming, soil health, or food systems. However, improved understanding of global potassium cycling may inform long-term perspectives on nutrient weathering, ocean-sediment interactions, and potassium availability in ancient agricultural contexts.

Key measures

Stable potassium isotope ratios (⁴¹K/³⁹K) in hydrothermal vent fluids; fractionation patterns relative to seawater baseline

Outcomes reported

The study characterised stable potassium isotope ratios (⁴¹K/³⁹K) in fluids from mid-ocean ridge hydrothermal vents. Findings are presented as implications for understanding modern and ancient potassium cycling in marine and terrestrial systems.
