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 …

The study of noble gases in oceanic basalts is central to understanding chemical
heterogeneity of the Earth's mantle and origin of the atmosphere. In the terrestrial …

This paper attempts to bridge this gap by presenting a User's Guide to, basalt discrimination
器 diagrams. It first deals with the requirements of sample collection, geochemical analysis …

Abstract Early History of Mantle GeochemistryUntil the arrival of the theories of plate
tectonics and seafloor spreading in the 1960s, the Earth's mantle was generally believed to …

Suprasubduction zone (SSZ) ophiolites display a consistent sequence of events during their
formation and evolution that suggests that they form in response to processes that are …

Plate processing at convergent margins plays a central role in the distribution of elements
among major earth reservoirs. The mechanisms by which this distribution occurs, however …

Abstract The Semail (Oman–United Arab Emirates) and other Tethyan-type ophiolites are
underlain by a sole consisting of greenschist-to granulite-facies metamorphic rocks. As …

Mid-ocean ridge basalts (MORB) from the Indian Ocean are characterized by higher
87Sr/86Sr and lower 206Pb/204Pb, on average, than Atlantic and Pacific MORB. These …

The plate tectonic cycle produces chemically distinct mid-ocean ridge basalts and arc
volcanics, with the latter enriched in elements such as Ba, Rb, Th, Sr and Pb and depleted in …

The Qinling–Dabie–Sulu orogen marks the junction between the North and South China
Blocks. However, the exact timing of the final coalescence of the North and South China …
