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 …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

Recycled ancient oceanic crust with variable amounts of aging, or inclusion of sediments of
differing types and origins has often been invoked as a source for present‐day ocean island …

Recycling of oceanic crust together with different types of marine sediments has become
somewhat of a paradigm for explaining the chemical and isotopic composition of ocean …

Abstract The Kerguelen hotspot (Indian Ocean) has produced basalt for∼ 130 Myr, among
the longest known volcanic records from a single source. New and published 40 Ar/39 Ar …

The Hf and Lu isotopic ratios of the zircon standard 91500 have been redefined by multiple
collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The chemical …

Oceanic plateaus form by mantle processes distinct from those forming oceanic crust at
divergent plate boundaries. Eleven drillsites into igneous basement of Kerguelen Plateau …

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 …

Oxygen isotope ratios are reported for olivine phenocrysts from sixty-seven samples of
ocean island basalts (OlBs), mid-ocean ridge basalts (MORBs), and related peridotites …

The basaltic basement of the large igneous province formed by the Kerguelen Plateau and
Broken Ridge in the southeastern Indian Ocean has been sampled by three Ocean Drilling …
