摘要: The past four years saw advances in a number of aspects hydrothermal chemistry. High temperature venting was documented at sites, association with the spectrum seafloor volcanic activity: slow to fast spreading normal ridges, seamounts, back arc settings; sediment-hosted and sediment-starved sites. Significant progress made description, both theoretical observational, geometry circulation nature water-rock reaction. Hydrothermal plumes received extensive study, expanding range anomalies demonstrating more clearly links sedimentation. Biological-chemical interactions began be explored quantitative way. Pore fluid advection on sedimented ridge flanks characterized though general question importance off-axis basalt-seawater interaction remains unresolved.
