    • Fingerprints of metamorphism in chromite: New insights from minor and trace elements 
      Colás, Vanessa; González Jiménez, José; Griffin, William L.; Fanlo, Isabel; Gervilla, Fernando; O'Reilly, Suzanne Y.; Pearson, Norman; Kerestedjian, Thomas N.; Proenza, Joaquín A. (Elsevier, 2014)
      subjected to high-pressure metamorphism defines a metamorphic signature. A two-stage process associated with the infiltration of fluids during retrogrademetamorphismfromeclogite- to amphibolite-facies has produced four ...
    • Fluid-present deformation aids chemical modification of chromite: Insights from chromites from Golyamo ... 
      Satsukawa, Takako; Piazolo, Sandra; González Jiménez, José; Colás, Vanessa; Griffin, William L.; O'Reilly, Suzanne Y.; Gervilla, Fernando; Fanlo, Isabel; Kerestedjian, Thomas N. (Elsevier, 2015)
      Chemical signatures of chromitites are commonly used to track the evolution of the Earth's mantle. However, chemical modification during deformation may have important implications for the interpretation of chromites' ...
    • Magmatic and Post-Magmatic Signatures of Chromian Spinels in Podiform Chromitites from the Cheshmeh-Bid ... 
      Eslami, Alireza; Ghaderi, Majid; Griffin, William L.; Gain, Sarah; Grieco, Giovanni; González Jiménez, José (Ofioliti, 2015)
      Podiform bodies of high-Cr chromitite in the Cheshmeh-Bid chromitite deposit are located at the mantle-lower crust transition zone (MTZ) of the Late Cretaceous Khajeh-Jamali ophiolitic massifs, Iran. The unaltered core ...
    • Re–Os isotopic constraints on the source of platinum-group minerals (PGMs) from the Vestřev pyrope-rich ... 
      Pasava, Jan; Malec, Jan; Griffin, William L.; González Jiménez, José (Elsevier, 2015)
      Mineralogical studies of the heavy fraction from a Holocene pyrope-rich garnet placer deposit at Vestřev (Krkonoše Piedmont Basin, Bohemian Massif) have identified the presence of very rare grains of platinum group ...
    • Thermal metamorphism of mantle chromites and the stability of noble‑metal nanoparticles 
      González Jiménez, José; Reich Morales, Martín; Camprubí, Antoni; Gervilla, Fernando; Griffin, William L.; Colás, Vanessa; O'Reilly, Suzanne Y.; Proenza, Joaquín A.; Pearson, Norman; Centeno García, Elena (Springer, 2015)
      The Loma Baya complex in south-western Mexico is a volume of chromitite-bearing oceanic mantle that records a complex metamorphic history, defined by a first stage of hydrous metamorphism overprinted by a short-lived thermal ...
    • Trace-element fingerprints of chromite, magnetite and sulfides from the 3.1 Ga ultramafic-mafic rocks of ... 
      Mukherjee, Ria; Mondal, Sisir K.; González Jiménez, José; Griffin, William L.; Pearson, Norman; O'Reilly, Suzanne Y. (Springer, 2015)
      The 3.1 Ga Nuggihalli greenstone belt in the Western Dharwar craton is comprised of chromitite-bearing sill-like ultramafic-mafic rocks that are surrounded by metavolcanic schists (compositionally komatiitic to komatiitic ...
