Lucky Strike hydrothermal field
Mid-Atlantic Ridge, near the Azores Triple Junction, Océan Atlantique (eaux portugaises, Açores)
Volcanogenic massive sulfidesFe, Zn, Cu (sulfures)
- Type
- Active basalt-hosted seafloor massive sulfides
Seafloor hydrothermal sulfides analysed for Sb by Rouxel et al. (2003), values published as ε123Sb. Chimneys and flanges with pyrite, marcasite, sphalerite and barite; sulfide δ123Sb of +0.24 to +0.61 ‰, above the lava-lake basaltic glass (+0.24 ‰) and close to seawater (+0.37 ‰): Sb partly inherited from seawater. Indicative coordinates.
