The journal Marine Geology has recently published a case study on a novel hydrothermal system that integrates underwater ROV observations, geophysical, mineralogical, geochemical and microbiological studies. Low temperature, shallow water hydrothermal fields were discovered in El Hierro Island. Hornito chimneys and secondary cones are active vents and mineralization areas. Fe-rich sediments were soon formed after the 2011-2012 submarine volcanic event. Microbial mediated minerals precipitation (iron-silica deposits) was revealed by high-resolution technics. The paper is a contribution to GeoERA-MINDeSEA WP3-Seafloor massive sulphides.
