Hydrothermal activity on near-arc sections of back-arc ridges: Results from the Mariana Trough and Lau Basin

Baker, Edward; Massoth, Gary; Nakamura, Ko-ichi; Embley, Robert; de Ronde, Cornel; Arculus, Richard


The spatial density of hydrothermal venting is strongly correlated with spreading rate on mid-ocean ridges (with the interesting exception of hot spot-affected ridges), evidently because spreading rate is a reliable proxy for the magma budget. This correlation remains untested on spreading ridges in back-arc basins, where the magma budget may be complicated by subduction-induced variations of the melt supply. To address this uncertainty, we conducted hydrothermal plume surveys along...[Show more]
