New geochemical data are presented for fresh lavas from off-axis seamounts east and west of the Valu Fa Ridge and from seamounts south of the propagating rift tip of the Valu Fa Ridge. Most seamount lavas are basaltic and thus more primitive than the

A submersible dive conducted on Volcano #1 located near 21 degrees 09'S-175 degrees 45'W on the Tonga Arc showed that the volcanic edifice with a caldera floor area of 30 km(2) located at and 450 m deep (b.s.l.=below sea level) was constructed recent

Submarine hydrothermal venting along mid-ocean ridges is an important contributor to ridge thermal structure, and the global distribution of such vents has implications for heat and mass fluxes from the Earth's crust and mantle and for the biogeograp

The ultraslow spreading Gakkel Ridge represents one of the most extreme spreading environments on the Earth. Full spreading rates there of 0.6–1.3 cm/year and Na8.0 in basalts of 3.3 imply an extremely low degree of mantle partial melting. For this

Geochemical and isotopic data of tholeiitic lavas from the northernmost volcanic deep, the Shaban Deep in the Red Sea rift suggest the presence of small-scale heterogeneities in the mantle underneath this part of the rift. The major and rare-earth el

The geochemistry of mid-oceanic ridge basalts from 86°N (Arctic Ocean) provides, for the first time, an insight into the composition of the mantle around the North Pole. Our data show the source region of the Arctic basalts to possess traces of an e
