Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

The mechanism of magmatransportat depth influences direction magma moves, the distance
it travels before freezing, the degree to which it communicates chemically with the host rock …

The influence of water on the dynamics of the oceanic upper mantle is re-evaluated based
on recent experimental constraints on the solubility of water in mantle minerals and earlier …

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 …

When Harry Hess first proposed the theory of seafloor spreading, he imagined that mantle
peridotite upwelling at midocean ridges reacted with water to form a serpentinite oceanic …

This paper reports experiments carried out between 1.5 and 2.3 GPa using synthetic
analogs of the molten peridotite system to investigate the effects of pressure (P), temperature …

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 …

We review physical and chemical constraints on the mechanisms of melt extraction from the
mantle beneath mid–ocean ridges. Compositional constraints from MORB and abyssal …
