    • 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 ...
    • 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 ...
    • Nanoscale partitioning of Ru, Ir, and Pt in base-metal sulfides from the Caridad chromite deposit, Cuba 
      González Jiménez, José; Deditius, Artur; Gervilla, Fernando; Reich Morales, Martín; Suvorova, Alexandra; Roberts, Malcolm; Roqué, Josep; Proenza, Joaquín A. (Walter de Gruyter GmbH, 2018)
      We report new results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides. The Ni-Fe-Cu base-metal ...
    • Platinum-group element and gold enrichment in soils monitored by chromium stable isotopes during weathering ... 
      Rivera, Javier; Reich Morales, Martín; Schoenberg, Ronny; González Jiménez, José; Barra, Fernando; Aiglsperger, Thomas; Proenza, Joaquín A.; Carretier, Sebastien (Elsevier B.V., 2018)
      Weathering of ultramafic rocks can lead to the formation of soil profiles with high contents of Fe, Ni, Co, platinum-group elements (PGE) and gold. Traditionally, these metal-rich soils are known as “laterites” and are ...
