TL;DR: In this paper, the authors evaluated the quality of available activity-composition models for silicate melts by calculating equilibrium constants for the exchange of albite and anorthite components between plagioclase and melt as functions of reciprocal temperature.

TL;DR: Analysis of neodymium isotopic data from the oldest remnants of Archean crust suggests that crustal recycling is important and that preserved continental crust comprises fragments of crust that escaped recycling.

TL;DR: In this article, the role of fractional crystallization in the origin of the rhyolite of Glass Mountain was investigated and the presence and composition of amphibole in magmatic inclusions preserve evidence for crystallization of the andesite at pressures of at least 200 MPa (6 km depth) under near H2O-saturated conditions.

TL;DR: The San Quintin Volcanic Field (SQVF) is unique for the Baja California peninsula as the only known location of intraplate-type mafic alkalic volcanism and the source of peridotitic and granulitic xenoliths.

TL;DR: Compositional and isotopic zoning patterns in plagioclase and amphibole phenocrysts from El Chichon eruptions reveal multiple cycles of country rock assimilation, magma injection, hybridization, and mixing.
