    • 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 ...
    • The pre-Mesozoic rocks of northern Chile: U-Pb ages, and Hf and O isotopes 
      Pankhurst, Robert J.; Hervé Allamand, Francisco; Fanning, C. Mark; Calderón, Mauricio; Niemeyer, Hans; Griem Klee, Susanne; Soto, Fernanda (Elsevier, 2016)
      Supposed pre-Mesozoic igneous and metamorphic rocks from northern Chile are reviewed in the light of twenty-one new SHRIMP U-Pb zircon age determinations. Metamorphic rocks from the precordillera upthrust belt mostly show ...
    • Resolving the paradigm of the late Paleozoic-Triassic Chilean magmatism: Isotopic approach 
      del Rey, A.; Deckart, Katja; Arriagada, C.; Martínez, F. (2016)
      The Andean orogenic cycle and its subduction-related magmatism along the southwestern margin of South America began during the early Jurassic after an accretionary history throughout Paleozoic times. The Chilean and ...
    • Zircon recycling and crystallization during formation of chromite- and Ni-arsenide ores in the subcontinental ... 
      González Jiménez, José; Cáceres Marchesi, Claudio; Griffin, William L.; Gervilla, Fernando; Belousova, Elena A.; Garrido, Carlos J.; Romero, Rurik; Talavera, Cristina; Leisen, Mathieu; O'Reilly, Suzanne Y.; Barra Pantoja, Luis Fernando; Martin, Laure (Elsevier, 2017)
      The ultramafic massifs of the Serrania de Ronda (namely Ronda, Ojen and Carratraca) are portions of Proterozoic (similar to 1.2-1.8 Ga) subcontinental lithospheric mantle (SCLM) affected by partial melting and infiltration ...
