AB The Tharsis supergiant massive sulphide deposits shows evidence of being formed by exhalative processes on the seafloor. The carbonate-siderite ore is interpreted as a bacterial mound while the bulk of the orebody seems to be formed in a brine pool by mixing of sulphur-depleted deep brines with H2S generated by hyperthermophile (archeo-)bacteria in the chemoclyne. This mechanism is significantly slower but geochemically much more effective that mound accretion on the seafloor and is interpreted as being the reason of the presence of supergiant massive sulphide deposits in the Iberian Pyrite Belt
