  • The intermediate step in fractionation trends of mildly alkaline volcanic suites: An experimental insight from the Pavin trachyandesite (Massif Central, France)
    CR Geosci. (IF 1.903) Pub Date : 2019-10-09
    Morgane Rondet; Caroline Martel; Jean-Louis Bourdier

    We examined magma storage conditions and eruptive dynamics for the trachyandesite (~58 wt% SiO2, 9–10 wt% alkalis) of the Pavin monogenetic volcano, a maar-like explosive crater belonging to a small group of youngest volcanoes in the Massif Central. By confronting the natural samples to experimental products, we constrained pre-eruptive conditions around 950–975 °C, 150–200 MPa (~5.5–7.0 km in depth)

  • Effect of anorthite on granite phase relations: Experimental data and models
    CR Geosci. (IF 1.903) Pub Date : 2019-11-15
    Michel Pichavant; Catherine Weber; Arnaud Villaros

    New experimental data on the effect of anorthite (An) on liquidus phase equilibria in the system Qz–Ab–Or are presented. The data were obtained for 5 wt% An added to variable Qz/Ab/Or compositions at 300 MPa and under H2O-saturated conditions. Crystal–liquid equilibria were determined for 13 synthetic glass compositions made from gels in experiments performed between 660 and 750 °C in cold-seal pressure

  • Titanite: A potential solidus barometer for granitic magma systems
    CR Geosci. (IF 1.903) Pub Date : 2019-11-15
    Saskia Erdmann; Rucheng Wang; Fangfang Huang; Bruno Scaillet; Kai Zhao; Hongsheng Liu; Yan Chen; Michel Faure

    Constraining crystallization pressure and thus intrusion depth of granites in various geodynamic settings remains challenging, yet important to further our understanding of magma system and crustal evolution. We propose that titanite, which is a common accessory in metaluminous and weakly peraluminous granites, can be used as a barometer if it crystallized in magmatic, near-solidus conditions and in

  • Crystal clustering in magmas: Insights from HP–HT experiments
    CR Geosci. (IF 1.903) Pub Date : 2019-11-15
    Laurent Arbaret; Misha Bystricky; Patrick Launeau

    We have studied by high-resolution X-ray Computed Tomography the effect of crystal clustering on the Shape-Preferred Orientation (SPO) development in synthetic magmas experimentally deformed at 300 MPa and 475–550°C. A fully connected solid network that could potentially induce the onset of yield strength is not achieved in these suspensions containing 16 vol% of crystals. The alumina grain population

  • Secular cooling and crystallization of partially molten Archaean continental crust over 1 Ga
    CR Geosci. (IF 1.903) Pub Date : 2019-10-14
    Olivier Vanderhaeghe; Célia Guergouz; Cécile Fabre; Stéphanie Duchêne; David Baratoux

    The protracted tectonic and magmatic record of cratons over the Archaean Eon has been classically interpreted in terms of long-lived shallow-dipping subduction or repeated mantle plumes. In this paper, we use the 1D conductive heat equation to model the evolution of the geotherm of a generic felsic-dominated Archaean cratonic nuclei solely considering the secular decay of radioactive isotopes (238U
