      Espinoza, Felipe; Morata Céspedes, Diego; Polvé, Mireille; Lagabrielle, Yves; Maury, René C.; de la Rupelle, Aude; Guivel, Christèle; Cotten, Joseph; Bellon, Hervé; Suárez, Manuel (Servicio Nacional de Geologia y Mineria, 2010)
      We present a chronological (K-Ar), petrologic and geochemical study (major and trace elements, Sr- Nd isotopes) of Middle Miocene (ca. 16-14 Ma) calc-alkaline rocks (basalts to andesites) extruded in the present-day back-arc ...
    • Silicic volcanism triggered by increased denudation rates in the Quaternary Andean arc of central Chile ... 
      Muñoz Gómez, Marcia; Payacán, Ítalo; Gutiérrez, Francisco; Farías Thiers, Marcelo; Charrier González, Reynaldo; Polvé, Mireille (Elsevier, 2020)
      In central Chile (33 degrees 50'-34 degrees 30'S), the Quaternary arc records a distinctive episode of silicic volcanism (SiO2 >70 wt%) that occurred during latest Pleistocene (0.1-1 Ma). This episode is recorded in several ...
