Evolution of an active sea-floor massive sulphide deposit
@article{You1998EvolutionOA, title={Evolution of an active sea-floor massive sulphide deposit}, author={Chen-Feng You and Mike J. Bickle}, journal={Nature}, year={1998}, volume={394}, pages={668-671} }
Hydrothermal circulation at oceanic spreading ridges causes sea water to penetrate to depths of 2 to 3 km in the oceanic crust where it is heated to ∼400 °C before venting at spectacular ‘black smokers’. These hydrothermal systems exert a strong influence on ocean chemistry, yet their structure, longevity and magnitude remain largely unresolved. The active Transatlantic Geotraverse (TAG) deposit, at 26° N on the Mid-Atlantic Ridge, is one of the largest, oldest and most intensively studied of…
