Covering 15,000,000 km2, the pan-European seas represent a promising new frontier for the exploration of mineral resources. The GeoERA-MINDeSEA consortium, a cooperative network of 12 Geological Surveys and Marine Institutes, is facing this exploration challenge. 688 seabed mineral occurrences are described in the MINDeSEA database, GIS cartographies and reports, containing valuable information on geology, metallogeny, critical raw materials prospectivity and mineral potential. Five types of mineral deposits are investigated, including seafloor massive sulphides, ferromanganese crusts,...

Thermo-compositional models of the West Gondwana cratons

Nils-Peter Finger , Mikhail K. Kaban , Magdala Tesauro , Walter D. Mooney & Maik Thomas
When Western Gondwana broke apart into the South American and African continents ca.120 Ma ago, some of its cratons were broken apart as well. Following the isopycnic hypothesis, their long-term stability and often neutral to positive buoyancy can be explained by the counteracting effects of cooling (density increase) and iron depletion (density decrease). To separate these effects, we created the presented models following an iterative integrated approach using mainly seismic and gravity data. In the...

Biomineralization processes in low-temperature, shallow-water hydrothermal vent at Tagoro submarine volcano, El Hierro Island (Central East Atlantic)

Blanca Rincón-Tomás , Francisco Javier González , Luis Somoza , James R. Hein , Teresa Medialdea , Esther Santofimia, Egidio Marino & Pedro Madureira
A novel hydrothermal system was discovered at the summit of the underwater Tagoro volcano at 89–120 m depth after the 2011–2012 eruption, characterized by the low-temperature venting of Fe-rich fluids that produced a seafloor draped by extensive Fe-flocculate deposits. The basanite-hornitos are capped by mm- to cm-thick hydrothermally derived Fe-oxyhydroxide sediment and contain micro-cracks and degasification vesicles filled by sulfides (mostly pyrite) and covered by sulfur-oxidizing bacterial mats. Electron microprobe studies on Fe-oxyhydroxide crusts show...
