Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Mid-ocean ridge basalts (MORB) are a consequence of pressure-release melting beneath
ocean ridges, and contain much information concerning melt formation, melt migration and …

This paper presents the first comprehensive major and trace element data for∼ 130 abyssal
peridotite samples from the Pacific and Indian ocean ridge–transform systems. The data …

Basaltic magmatism is a common feature of dynamically active terrestrial planets. The
compositions of basalts reflect the temperatures and pressures of magma generation …

Several methods have been developed to assess the thermal state of the mantle below
oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of …

Geochemical data have been interpreted as requiring that a significant fraction of the melting
in MORB source regions takes place in the garnet peridotite field, an inference that places …

We document compositions of minerals and melts from 3 GPa partial melting experiments on
two carbonate-bearing natural lherzolite bulk compositions (PERC: MixKLB-1+ 2· 5 wt …

This paper presents the results of the first quantitative petrological modelling of abyssal
peridotites. The mantle beneath a ridge may be considered as two regions:(1) the melting …

Abstract The late Permian Emeishan large igneous province (ELIP) covers∼ 0.3× 10 6 km 2
of the western margin of the Yangtze Block and Tibetan Plateau with displaced, correlative …
