Model ages calculated assuming initial (210Pb/226Pb) = 1.8–2.0 further constrain the timing of eruption, suggesting that more than half of the lavas erupted within the past 60 years. When combined with complementary data (side-scan sonar, lava flow morphology, tectonic mapping), this high-resolution record provides fundamental time constraints for interdisciplinary studies examining oceanic crustal construction and development of the hydrothermal system in the ABE vent field. Notably the youngest samples cluster around the active vent sites indicating that the ABE vent site’s location is a direct consequence of this concentrated young volcanism. This study is the first high resolution U-series study of a seafloor vent site and demonstrates the potential of using (210Pb/226Ra) for the determination of lava ages for young submarine lavas in spreading environments with active hydrothermal venting. As such these (210Pb/226Ra) measurements hold the promise for addressing in far greater detail the connections between spreading ridge eruptive and hydrothermal activity on the decadal to century time scales.]]> https://www.frontiersin.org/articles/10.3389/fgeoc.2023.1334490 https://www.frontiersin.org/articles/10.3389/fgeoc.2023.1334490 2024-01-12T00:00:00Z Methods Alban PetitjeanChristophe ThomazoOlivier MussetIvan JovovicPierre SansjofreKalle Kirsimäe
