High-resolution bathymetric surveys, bottom photography and sample analyses show that Loihi Seamount at the southernmost extent of the Hawaiian ‘hotspot’ is an active, young submarine volcano that is probably the site of an emerging Hawaiian island. 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… 

Submarine Hydrothermal Mineral Systems

Present-day, active submarine hydrothermal effluents, at spreading centres (mid-ocean ridges) and in oceanic volcanic arcs and back-arcs, are of considerable interest because they provide a window

Loihi Seamount, Hawaii: a mid-plate volcano with a distinctive hydrothermal system

The initial discovery of deep-sea hydrothermal vents at the Galapagos Rift1,2 has resulted in a decade of exploration and experimentation. Subsequent discoveries in the Pacific3–8 and Atlantic9 ocean

Geology of an active hot spot: Teahitia-Mehetia region in the South Central Pacific

The Teahitia-Mehetia hot spot region located in the southeastern extension of the Society Islands chain, near 18° S–148° W consists of several active volcanoes. The distribution of recent volcanic

Hydrothermal activity on the summit of Loihi Seamount, Hawaii

Oceanographic studies including CTD survey of warm sites and bottom photography confirmed several hydrothermal fields on the summit of Loihi Seamount, Hawaii. Warm water venting at these sites forms

Seismicity and surface deformation of Mauna Loa Volcano, Hawaii

Changing patterns of seismicity and surface deformation indicate that magma is being injected and stored in a shallow reservoir beneath the summit, and that the probability of an eruption is

Abundance of Hydrothermal Mineral Deposits on Seamounts Inferred From Seamounts Petrologic Characteristics and Abundances

In this short paper we attempt to make crude estimates of the amounts of sulfide mineral precipitates on off-ridge seamounts relative to the amounts precipitated from ridge crest hydrothermal
