Basaltic volcanism'samples' the Earth's mantle to great depths, because solid-state
convection transports deep material into the (shallow) melting region. The isotopic and trace …

Basalt geochemistry can be used as a diagnostic indicator for determining the tectonic
setting of origin, because specific plate tectonic settings often impart distinctive geochemical …

ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets
stability. Impacts of biodiversity on population dynamics and ecosystem functioning have …

We report new Hf (and Nd) data for more than 100 sedimentary samples, recent to Archean
in age, from a wide range of depositional environments. These data document the behavior …

Many oceanic island basalts show sublinear subparallel arrays in Sr-Nd-Pb isotopic space.
The depleted upper mantle is rarely a mixing end-member of these arrays, as would be …

his book is intended for graduate students of the Earth Sciences who require a T

Abstract The Hawaiian–Emperor Seamount Chain (ESC), in the northern Pacific Ocean, was
produced during the passage of the Pacific Plate over the Hawaiian hotspot. Major and trace …

Abstract Ocean Drilling Program (ODP) Leg 183 was designed to investigate the origin and
evolution of the large igneous province composed of the Kerguelen Plateau and Broken …
