Volcanoes play a key role in the cycling of volatile metals (eg, chalcophile elements such as
Tl, Pb, and Cu and metalloids such as As, Te, and Se) on our planet. Volatile metals and …

The recognition of abundant and widespread hydrothermal activity and associated unique
life-forms on the ocean floor is one of the great scientific discoveries of the latter half of the …

A global selection of 56 mid-ocean ridge basalt (MORB) glasses were analysed for Li and B
abundances and isotopic compositions. Analytical accuracy and precision of analyses …

Hydrothermal activity at mid‐ocean ridge spreading centers has an influence on all aspects
of oceanography. The heat input from these systems affects the mid‐depth circulation of the …

The mid-ocean ridge (MOR) is the largest, most continuous volcanic system on Earth, yet we
have directly observed, mapped or sampled less than one percent of its total surface area …

Subduction of oceanic crust and the formation of volcanic arcs above the subduction zone
are important components in Earth's geological and geochemical cycles. Subduction …

In 1991, vent fluids were sampled from 10 high temperature hydrothermal vent sites within
weeks of a volcanic eruption/dike intrusion on the East Pacific Rise, between 9° and 10° …

STUDIES of sea-floor hydrothermal vent fluids have shown them to have stable
characteristics on a decade timescale1, with temperatures in the range 350±30° C (ref. 2) …

Interpretation of U-series disequilibria in midocean ridge basalts is highly dependent on the
bulk partition coefficients for U and Th and therefore the mineralogy of the mantle source …

Two-thirds of Earth's surface is formed at mid-ocean ridges, yet sea-floor spreading events
are poorly understood because they occur far beneath the ocean surface. At 9° 50'N on the …
