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 …

Petrogenesis of Andesites ADS Classic is now deprecated. It will be completely retired in
October 2019. This page will automatically redirect to the new ADS interface at that point …

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 …

Various petrogenetic schemes have been proposed for A-type granitic and volcanic rocks,
many involving melting of I-type granites or their residual sources. These models can be …

Regional averages of the major element chemistry of ocean ridge basalts, corrected for low‐
pressure fractionation, correlate with regional averages of axial depth for the global system …

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 …

The geochemical character of the mantle wedge in convergent margin settings is
investigated using the high field strength and transition elements Ti, Zr, V, Sc and Y in …

The continental crust has an andesitic composition with high Mg/(Mg+ Fe) and Ni contents
which may be too high to have formed by differentiation of basaltic magmas. Instead, mantle …
