    • Dynamics and physical parameters of the Lastarria debris avalanche, Central Andes 
      Rodríguez, Inés; Páez, Jerson; Van Wyk De Vries, Maximillian; Van Wyk de Vries, Benjamin; Godoy Neira, Benigno (Elsevier, 2020)
      Volcanic debris avalanches are extremely destructive phenomena, with the potential to travel many kilometers from their source region, either as rockslides or as mass flows. Given that they may even be triggered at inactive ...
    • Eruptive history of La Poruna scoria cone, Central Andes, Northern Chile 
      Marín, Carolina; Rodríguez, Inés; Godoy, Benigno; González Maurel, Osvaldo; Le Roux, Petrus; Medina, Eduardo; Bertin, Daniel (Springer, 2020)
      New stratigraphic, lithological and petrographic analyses of La Poruna scoria cone (21 degrees 53 ' S-68 degrees 30 ' W, Central Andes, northern Chile) allow the reconstruction of the eruptive sequence of this monogenetic ...
    • Geological evolution of Paniri volcano, central Andes, Northern Chile 
      Godoy, Benigno; Lazcano, José; Rodríguez, Inés; Martínez, Paula; Parada, Miguel A.; Le Roux, Petrus; Wilke, Hans-Gerhard; Polanco, Edmundo (Elsevier, 2018-07)
      Paniri volcano, in northern Chile, belongs to a volcanic chain trending across the main orientation of the Central Andean volcanic province. Field work mapping, stratigraphic sequences, and one new Ar-40/Ar-39 and eleven ...
    • Geomorphology, lithofacies, and block characteristics to determine the origin, and mobility, of a debris ... 
      Godoy, Benigno; Rodríguez, Inés; Pizarro, Marcela; Rivera, Germain (Elsevier, 2017)
      Understanding the evolution of a volcanic edifice is important in establishing its associated geological hazards. Apacheta and Aguilucho volcanoes, northern Chile, formed a volcanic complex with known fumaroles and geo-thermal ...
    • Magmatic differentiation at La Poruña scoria cone, Central Andes, northern Chile: Evidence for assimilation ... 
      González Maurel, Osvaldo; Godoy, Benigno; Le Roux, Petrus; Rodríguez, Inés; Marín, Carolina; Menzies, Andrew; Bertin, Daniel; Morata Céspedes, Diego; Vargas, Marina (Elsevier B.V., 2019)
      La Poruña (21°53′S; 68°30′W) is a 140 m high scoria cone composed of pyroclastic material and an extensive basaltic-andesite to andesite lava flow that is up to 8 km in length. Automated mineralogical analysis describes a ...
    • Upper crustal differentiation processes and their role in 238U-230Th disequilibria at the San Pedro-Linzor ... 
      Godoy, Benigno; McGee, Lucy; González Maurel, Osvaldo; Rodríguez, Inés; Roux, Petrus le; Morata Céspedes, Diego; Menzies, Andrew (Elsevier, 2020)
      U-series data are combined with major and trace element constraints to construct a detailed view of the magmatic system feeding the San Pedro-Linzor volcanic chain, aiding the understanding of how stratovolcanoes in extremely ...
