    • Fe-Ni-bearing serpentines from the saprolite horizon of Caribbean Ni-laterite deposits: new insights from ... 
      Villanova de Benavent, Cristina; Domenech, Cristina; Tauler, Esperança; Gali, Salvador; Tassara, Santiago; Proenza, Joaquín A. (Springer, 2017)
      Fe-Ni-bearing serpentine from the saprolite horizon is the main Ni ores in hydrous silicate-type Ni laterites and formed by chemical weathering of partially serpentinized ultramafic rocks under tropical conditions. During ...
    • Fluxing of mantle carbon as a physical agent for metallogenic fertilization of the crust 
      Blanks, Daryl E.; Holwell, David A.; Fiorentini, Marco L.; Moroni, Marilena; Giuliani, Andrea; Tassara, Santiago; González Jiménez, José M.; Boyce, Adrián J.; Ferrari, Elena (Nature, 2020)
      Magmatic systems play a crucial role in enriching the crust with volatiles and elements that reside primarily within the Earth’s mantle, including economically important metals like nickel, copper and platinum-group ...
    • Highly siderophile elements mobility in the subcontinental lithospheric mantle beneath southern Patagonia 
      Tassara, Santiago; González Jiménez, José M.; Reich Morales, Martín; Saunders, Edward; Luguet, Ambre; Morata Céspedes, Diego; Grégoire, Michel; van Acken, David; Schilling, Manuel E.; Barra Pantoja, Luis; Nowell, Geoff; Corgne, Alexandre (Elsevier, 2018)
      Peridotite xenoliths collected from alkali basalts in the Argentinian Patagonia reveal the existence of an ancient depleted Paleoproterozoic mantle that records a subsequentmultistage metasomatic history.Metasomatismis ...
    • Magmatic platinum nanoparticles in metasomatic silicate glasses and sulfides from Patagonian mantle xenoliths 
      González-Jiménez, José María; Roqué-Rosell, Josep; Jiménez-Franco, Abigail; Tassara, Santiago; Nieto, Fernando; Gervilla, Fernando; Baurier, Sandra; Proenza, Joaquín A.; Saunders, Edward; Deditius, Artur P.; Schilling, Manuel E.; Corgne, Alexandre (Springer Verlag, 2019)
      Platinum-rich nanonuggets (s.l., nanoparticles) are commonly produced in experiments attempting to quantify the solubility or partitioning of noble metals in silicate and sulfide melts. However, it has been thought that ...
    • Plume subduction interaction forms large auriferous provinces 
      Tassara, Santiago; González Jiménez, José; Reich Morales, Martín; Schilling, Manuel E.; Morata Céspedes, Diego; Begg, Graham; Saunders, Edward; Griffin, William L.; O'Reilly, Suzanne Y.; Gregoire, Michel; Barra Pantoja, Luis Fernando; Corgne, Alexandre (Nature Publishing Group, 2017)
      Gold enrichment at the crustal or mantle source has been proposed as a key ingredient in the production of giant gold deposits and districts. However, the lithospheric-scale processes controlling gold endowment in a given ...
    • 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. ...
