- Abstract:
- This project will use MC-ICP-MS and TIMS determinations of U-series isotopes to provide a precise and robust chronology of hydrothermal events in the TAG sulphide mound on the Mid-Atlantic Ridge. The temporal evolution, and episodicity of ocean ridge hydrothermal systems is a direct reflection of their deep structure, knowledge of which is critical to understanding the magnitude of geochemical fluxes between the solid Earth, hydrosphere and atmosphere. The research will test the integrity of 234U-230Th ages on sulphides by comparing 234U-230Th ages with 230Th-226Ra ages. The ultimate objective is to provide an accurate chronology for hydrothermal minerals from the TAG mound and define the episodicity of the high-temperature events.
