    • A widespread compositionally bimodal tephra sourced from Volcán Melimoyu (44°S, Northern Patagonian Andes): ... 
      Geoffroy, C.; Alloway, B.; Amigo, A; Parada, M.; Gutierrez, F.; Castruccio, A.; Pearce, N.; Morgado, E.; Moreno Moncada, Patricio (Elsevier Ltd, 2018)
      We describe the stratigraphy, age, constituent geochemistry and phenocryst thermobarometry of a closely spaced Holocene tephra couplet from Volcán Melimoyu (VMm), located in the Northern Patagonian Andes. The lower tephra ...
    • Post-melting oxidation of highly primitive basalts from the southern Andes 
      Tassara, Santiago; Reich Morales, Martín; Cannatelli, Claudia; Konecke, B. A.; Kausel Kausel, Domínica; Morata Céspedes, Diego; Barra, Fernando; Simon, A. C.; Fiege, A.; Morgado, E.; Leisen, Mathieu (Pergamon-Elsevier, 2020)
      The oxygen fugacity (fO(2)) of the Earth's upper mantle and its melting products is an important parameter in the geochemical evolution of arc magmas and their connection with the continental crustal construction and growth. ...
    • Transient shallow reservoirs beneath small eruptive centres: Constraints from Mg-Fe interdiffusion in olivine 
      Morgado, E.; Parada Reyes, Miguel; Morgan, D. J.; Gutiérrez, F.; Castruccio, A.; Contreras, C. (Elsevier, 2017)
      Small eruptive centres commonly have more primitive lavas than those associated with stratovolcanoes, an observation that has been taken to indicate a short magma residence in the crust relative to those reservoirs below ...
