One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Continental arcs are the sites of production of continental crust, but the origin of these
magmatic systems is not well understood. Although a number of processes have been …

Calcic, igneous amphiboles are of special interest as their compositional diversity and
common occurrence provide ample potential to investigate magmatic processes. But not all …

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

Magmatic fertility to generate porphyry-and high-sulfidation copper ore deposits generally
develops, not at the scale of individual igneous complexes, but rather at the scale of …

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 …

Differentiation of mantle-derived, hydrous, basaltic magmas is a fundamental process to
produce evolved intermediate to SiO 2-rich magmas that form the bulk of the middle to …

Differentiation of hydrous primary, mantle-derived magmas is a fundamental process to
generate evolved intermediate to SiO2-rich compositions forming the bulk of the continental …

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 …

Amphibole thermodynamics are approximated with the symmetric formalism (regular
solution model for within-site non-ideality and a reciprocal solution model for cross-site …
