Rare earth elements as indicators of hydrothermal processes within the East Scotia subduction zone system

Rare earth elements as indicators of hydrothermal processes within the East Scotia subduction zone system

The East Scotia subduction zone, located in the Atlantic sector of the Southern Ocean, hosts a number of hydrothermal sites in both back-arc and island-arc settings. High temperature (>348°C) ‘black smoker’ vents have been sampled at three locations along segments E2 and E9 of the East Scotia bac...

Zusammenfassung:The East Scotia subduction zone, located in the Atlantic sector of the Southern Ocean, hosts a number of hydrothermal sites in both back-arc and island-arc settings. High temperature (>348°C) ‘black smoker’ vents have been sampled at three locations along segments E2 and E9 of the East Scotia back-arc spreading ridge, as well as ‘white smoker’ (
