Martos, Rubén ; Ortega Menor, Lorena ; Gervilla, Fernando ; Piña García, Rubén ; Monterrubio, Serafín ; Lunar Hernández, Rosario ; Albert, Helena | Sociedad Geológica de España | 2010The Cerro Cabrera and Sierra Cabeza Gorda peridotite massifs (Calzadilla de los Barros, Badajoz) comprise serpentinites hosting podiform chromite mineralization and have been interpreted as part of an ophiolitic slab. The chromites are Al-rich a[...]texto impreso

Piña García, Rubén ; Gervilla, Fernando ; Ortega Menor, Lorena ; Lunar Hernández, Rosario | Shigen Chishitsu Gakkai | 2012After the discovery of theAguablanca ore deposit (the unique Ni–Cu mine operating in SW Europe), a number of mafic-ultramafic intrusions bearing Ni–Cu magmatic sulfides have been found in the Ossa–Morena Zone of the Iberian Massif (SW Iberian Pe[...]texto impreso
González Jiménez, José María ; Piña García, Rubén ; Kerestedjian, Thomas N. ; Gervilla, Fernando ; Borrajo, Iñigo ; Farré de Pablo, Julia ; Proenza, Joaquín ; Tornos, Fernando ; Roqué, Josep ; Nieto, Fernando | Elsevier | 2021-01Porphyry Cu can contain significant concentrations of platinum-group elements (PGE: Os, Ir, Ru, Rh, Pt, Pd). In this study, we provide a comprehensive in situ analysis of noble metals (PGE, Au, Ag) for (Cusingle bondFe)-rich sulfides from the El[...]texto impreso
Piña García, Rubén ; Gervilla, Fernando ; Ortega Menor, Lorena ; Lunar Hernández, Rosario | Springer Science Business Media | 2007The Aguablanca Ni-Cu-(PGE) magmatic sulphide deposit is associated with a magmatic breccia located in the northern part of the Aguablanca gabbro (SW, Iberia). Three types of ores are present: semi-massive, disseminated, and chalcopyrite-rich vei[...]texto impreso
Piña García, Rubén ; Romeo Briones, Ignacio ; Ortega Menor, Lorena ; Lunar Hernández, Rosario ; Capote del Villar, Ramón ; Gervilla, Fernando ; Tejero López, Rosa ; Quesada Ochoa, Cecilio | Geological Society of America | 2010-05A model is proposed for the origin and emplacement of the ca. 341 Ma Aguablanca magmatic Ni-Cu-(platinum group element [PGE]) sulfi de deposit (SW Iberia) integrating petrological, geochemical, structural, and geophysical data. The Aguablanca de[...]texto impreso
Piña García, Rubén ; Gervilla, Fernando ; Helmy, Hassan ; Fonseca, Raúl O.C. ; Ballhaus, Chris | Mineralogical Society of America | 2020Evidence of immiscibility between arsenide and sulfide melts has been observed both in experimental studies and natural samples from several localities worldwide (e.g., Ronda, Spain; Beni Bousera, Morocco; Dundonald Beach South, Canada). Platinu[...]texto impreso
Piña García, Rubén ; Gervilla, Fernando ; Barnes, Sarah-Jane ; Ortega Menor, Lorena ; Lunar Hernández, Rosario | Society of Economic Geologists (U.S.) | 2013The partition coefficients of platinum group elements (PGE) and chalcophile elements Au, Re, Ag, Se, Bi, Te, and Sb, between arsenide and sulfide phases (DAs/sulf) have been estimated by measuring in situ concentrations of these elements using l[...]texto impreso
Piña García, Rubén ; Gervilla, Fernando ; Barnes, Sarah-Jane ; Ortega Menor, Lorena ; Lunar Hernández, Rosario | E. Schweizerbart'sche Verlagsbuchhandlung | 2013Despite the fact that pyrite is a relatively common phase in Ni-Cu-Platinum-Group Elements (PGE) magmatic sulphide deposits, it has been neglected in the studies on PGE distribution in favour of pyrrhotite, pentlandite and chalcopyrite.
