    • Devonian magmatism in the accretionary complex of southern Chile 
      Hervé Allamand, Francisco; Calderón, M.; Fanning, C.M.; Pankhurst, Robert J.; Fuentes, F.; Rapela, Carlos; Correa Orphanopoulos, Jorge; Quezada Pozo, Paulo; Marambio Pizarro, Camila (Geological Society of London, 2016)
      Supposed or potential Devonian igneous rocks in the accretionary complex of southern Chile were investigated using sensitive high-resolution ion microprobe U-Pb dating of zircon, with Hf- and O-isotope analyses of selected ...
    • Forearc density structure of the overriding plate in the northern area of the giant 1960 Valdivia earthquake 
      Maksymowicz Jeria, Andrei; Montecinos Cuadros, Daniela Patricia; Díaz Alvarado, Daniel Alejandro; Segovia Baldovino, María José; Reyes Torres, Tomás Hernán (Copernicus, 2022)
      The objective of this work is to analyse the density structure of the continental forearc in the northern segment of the 1960 Mw 9.6 Valdivia earthquake. Regional 2D and local 3D density models have been obtained from ...
    • The first andean compressive tectonic phase: sedimentologic and structural analysis of mid-cretaceous ... 
      Boyce Marto, Daniel; Charrier González, Reynaldo; Farías Thiers, Marcelo (AGU, 2020)
      We document the effects of major mid-Cretaceous to Late Cretaceous compression within the volcanic arc of the western Gondwanan margin. The thinned Early Cretaceous Andean margin underwent rapid thickening and shortening-related ...
