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 ; Lunar Hernández, Rosario ; Ortega Menor, Lorena ; Gervilla, F. ; Alapieti, T. ; Martínez, C. | Society of Economic Geologists (U.S.) | 2006Aguablanca (southwest Spain) is the first economic Ni-Cu-(PGE) deposit found in southern Europe. Two features make it an unusual example of magmatic sulfide ore: it is related to the development of an Andeantype continental magmatic arc, and it [...]texto impreso
The Main Sulfide Zone (MSZ) of the Great Dyke of Zimbabwe hosts the world’s second largest resource of platinum-group elements (PGE) after the Bushveld Complex in South Africa. The sulfide assemblage of the MSZ comprises pyrrhotite, pentlandite,[...]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. An examp[...]texto impreso
Barnes, Stephen J. ; Staude, Sebastian ; Le Vaillant, Margaux ; Piña García, Rubén ; Lightfoot, Peter C. | Elsevier | 2018-10Much of the value of magmatic Ni-Cu-PGE sulfide orebodies is contained within massive or semi-massive ores that show a wide variety of textural relationships to included or adjacent silicate rocks. We identify five mutually gradational textural [...]texto impreso
The intrusion-hosted Ni-Cu sulfide deposit at Aguablanca in south-western Spain contains a high proportion of ores in the form of sulfide-matrix ore breccias. These are polymict, comprising autoliths and xenoliths in sulfide-rich and/or sulfide-[...]texto impreso
Chinchilla Benavides, Darío ; Ortega Menor, Lorena ; Piña García, Rubén ; Merinero Palomares, Raúl ; Moncada, Daniel ; Bodnar, Robert J. ; Quesada Ochoa, Cecilio ; Valverde, Antonio ; Lunar, Rosario | Elsevier | 2016-03The Patricia ore deposit represents an unusual example of economic Zn–Pb–Ag mineralization at the northernmost end of the Late Eocene–Oligocene metallogenic belt in Chile. It is hosted by volcano-sedimentary units, which are typically tuffaceous[...]texto impreso

Romeo Briones, Ignacio ; Lunar Hernández, Rosario ; Capote del Villar, Ramón ; Quesada Ochoa, Cecilio ; Dunning, Gregory R. ; Piña García, Rubén ; Ortega Menor, Lorena | Geological Society of London. | 2006New U–Pb zircon ages from the Santa Olalla Igneous Complex have been obtained, which improve the knowledge of the precise timing of Variscan magmatism in the Ossa–Morena Zone, SW Iberia. This complex has a special relevance as it hosts the most [...]
