Journal ArticleDOI
Trace element signature of subduction-zone fluids, melts and supercritical liquids at 120–180 km depth
TL;DR: Measurements of the composition of fluids and melts equilibrated with a basaltic eclogite at pressures equivalent to depths in the Earth and temperatures of 700–1,200 °C constrain the recycling rates of key elements in subduction-zone arc volcanism.
Journal ArticleDOI
Serpentine Stability to Mantle Depths and Subduction-Related Magmatism
Peter Ulmer,V. Trommsdorff +1 more
TL;DR: Results of high-pressure experiments on samples of hydrated mantle rocks show that the serpentine mineral antigorite is stable to ∼720�C at 2 gigapascals, to ∼690 �C at 3 gigapascalals, and to ∼620�C to 5 gigapASCals.
Journal ArticleDOI
Igneous garnet and amphibole fractionation in the roots of island arcs: experimental constraints on andesitic liquids
TL;DR: In this article, the role of garnet and amphibole fractionation at conditions relevant for the crystallization of magmas in the roots of island arcs was evaluated on a synthetic andesite at conditions ranging from 0.8 to 1.2 GPa.
Journal ArticleDOI
Non-Newtonian rheology of crystal-bearing magmas and implications for magma ascent dynamics
Luca Caricchi,L. Burlini,Peter Ulmer,Taras Gerya,Melissa Vassalli,Melissa Vassalli,Paolo Papale +6 more
TL;DR: In this article, a series of high-temperature, high-pressure experiments at conditions relevant for volcanic conduits were undertaken to investigate the rheology of magma with crystal fractions varying between 0.5 and 0.8 at different strain-rate conditions.
Journal ArticleDOI
Fractional crystallization of primitive, hydrous arc magmas: an experimental study at 0.7 GPa
TL;DR: In this article, the results of fractional crystallization experiments conducted in a piston cylinder apparatus at 0.7 GPa for hydrous, calc-alkaline to arc tholeiitic magmas were reported.
