González, F.J. ; Somoza, L. ; Lunar Hernández, Rosario ; Martínez Frías, Jesús | Instituto Geológico y Minero de España | 2006En este trabajo presentamos el primer descubrimiento y recolección de nódulos de Fe-Mn en el Golfo de Cádiz. Los nódulos recuperados (más de 500 muestras) se han encontrado sobre corteza continental en los alrededores de los montículos fangoso-g[...]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 ; 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
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
Romeo Briones, Ignacio ; Capote del Villar, Ramón ; Lunar Hernández, Rosario ; Cayzer, N. | Elsevier Science B.V., Amsterdam. | 2007Electron Back-Scatter Diffraction (EBSD), which provides an easy way of acquiring large numbers of individual crystallographic orientation data from different phases, has been applied to the study of magmatic fabrics. Using this technique, the c[...]texto impreso

Ortega Menor, Lorena ; Lunar Hernández, Rosario ; García Palomero, F. ; Moreno, Teresa | Mineralogical Association of Canada | 2004The Aguablanca Ni–Cu–PGE ore deposit, in southwestern Iberia, has a magmatic origin, and has been reworked by later skarn-related hydrothermal activity. Base-metal sulfides are associated with igneous cumulates displaying subvertical layering co[...]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 [...]
