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 …

This chapter summarizes the oxygen isotope geochemistry of terrestrial basalts and their
mantle sources, including the conceptual framework for interpreting such data and the …

Pressure is one of the key variables that controls magmatic phase equilibria. However,
estimating magma storage pressures from erupted products can be challenging. Various …

An updated and expanded data set that consists of 214 plagioclase-liquid equilibrium pairs
from 40 experimental studies in the literature is used to recalibrate the thermodynamic …

A revised regular solution-type thermodynamic model for twelve-component silicate liquids
in the system SiO 2-TiO 2-Al 2 O 3-Fe 2 O 3-Cr 2 O 3-FeO-MgO-CaO-Na 2 OK 2 OP 2 O 5-H …

Phase relations of natural aphyric high-alumina basalts and their intrusive equivalents were
determined through rock-melting experiments at 2 kb, H 2 O-saturated with f O 2 buffered at …

This paper introduces Petrolog3, software for modeling (1) fractional and equilibrium
crystallization,(2) reverse fractional crystallization at variable pressure, melt oxidation state …

A systematic study of rare earth and other trace elements in discrete diopsides from residual
abyssal peridotites sampled from 5000 km of ocean ridge demonstrates that they are the …

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 …

Understanding mantle melting above subduction zones requires an evaluation of the
behaviour of elements for which the mantle contribution greatly exceeds any subduction …
