Hydrothermal deposits sampled from the active summit rift system were probably formed by precipitation from cooling vent fluids or during cooling and oxidation of high-temperature polymetallic sulphide assemblages. No exotic benthic fauna were found to be associated with the presently active hydrothermal vents mapped.completedEconomic geology, geology of ore depositsactive volcanoesclay mineralogyclay mineralsDeep Sea Drilling ProjectDSDP Site 424East PacificEast Pacific Ocean Islandseconomic geologygoethiteHawaiihydrothermal alterationhydrothermal processesIPODiron oresLeg 54Loihi Seamountmanganese oresmetal oresmetasomatismmineral deposits, genesisnontroniteNorth American PacificNorth PacificNortheast Pacificocean floorsOceaniaoceanographyoxidesPacific Oceanpolymetallic oresPolynesiarift zonesseamountssheet silicatessilicatessmectitestructural geologytectonicsUnited Statesurn:org.iodp:exp:54urnlargerWorkCitationcampaignurn:org.iodp:exp:54:site:424urnlargerWorkCitationstudyurn:org.iodp:exp:54urnlargerWorkCitationcampaignEnglishgeoscientificInformation-179.0000-86.07490.353728.3000HawaiiLoihi Seamount
