Ruiz Roso, Jesús ; García Lorenzo, Mari Luz ; Castiñeiras García, Pedro ; Muñoz Martín, Alfonso ; Crespo Feo, Elena | MDPI | 2020-12-14Abandoned mine wastes, containing high sulfide contents, are of particular concern because of the formation of acid mine drainage (AMD), becoming an active and harmful point source of potentially toxic elements (PTEs) to the environment. A detai[...]texto impreso
García Lorenzo, Mari Luz ; Crespo Feo, Elena ; Esbrí Victor, José María ; Higueras, Pablo ; Grau, Patricia ; Crespo, Isabel ; Sánchez Donoso, Ramón | MDPI | 2019-06-05This work presents an integral methodological approach to assess the environmental potential hazards posed by metals and metalloids hosted by spolic technosols derived from old tailings from a mining operation for galena (PbS, with high Ag conte[...]texto impreso

Fernández Caliani, J.C. ; Crespo Feo, Elena ; Rodas, Magdalena ; Fernández Barrenechea, José María ; Luque del Villar, Francisco Javier | Clay Minerals Society | 2004This paper describes a rare occurrence of nontronite associated with sulfide-bearing felsic metavolcanics, providing evidence of colloidal deposition in open spaces as result of a low-temperature water-rock interaction. Microbotryoidal masses of[...]texto impreso
Rodriguez Soto, Pablo ; Tsige Beyebe, Meaza ; Insua Arévalo, Juan Miguel ; Martínez Díaz, José J. ; Rodríguez Escudero, Emilio ; Jurado, María José ; Crespo Feo, Elena ; Jiménez Molina, David | EGU General Assembly | 2017Here we present the results of the mechanical and mineralogical study of the fault rock of the Alhama de Murcia fault. This fault is one of the most active faults in the Iberian Peninsula. It shows segments partially formed by exhumed fine grain[...]texto impreso
Crespo Feo, Elena ; Luque del Villar, Francisco Javier ; Fernández Barrenechea, José María ; Rodas, Magdalena | Mineralogical Society (Great Britain) | 2006This paper examines the effects of shear stress on the structuralparameters that define the ‘crystallinity’ of graphite. The results show that highly crystalline graphite samples ground for up to 120 min do not undergo detectable changes in the [...]texto impreso
Crespo Feo, Elena ; Luque del Villar, Francisco Javier ; Fernández Barrenechea, José María ; Rodas, Magdalena | Mineralogical Society (Great Britain) | 2005This paper describes a vein-shaped graphite occurrence in which, for the first time, the geological, mineralogical and isotopic evidence support its formation by physical remobilization of previously formed syngenetic graphite. The deposit studi[...]texto impreso
Oyarzun, Roberto ; López García, José Ángel ; Crespo Feo, Elena ; Lillo, Javier | Springer | 2018-03The southern end of Genoveses Bay (Cala de Genoveses) in Almería (SE Spain) hosts one of the most spectacular examples in Europe of combined (from base to the top), ignimbrite, surge, and pumice-ash fall deposits, forming a world-class outcrop o[...]texto impreso
Crespo Feo, Elena ; Luque del Villar, Francisco Javier ; Fernández Rodríguez, Carlos ; Rodas, Magdalena ; Díaz Azpiroz, Manuel ; Fernández Caliani, J.C. ; Fernández Barrenechea, José María | Cambridge University Press | 2004The significance of syngenetic and epigenetic graphite occurrences from the Variscan hightemperature/ low-pressure Aracena Metamorphic Belt is discussed in the framework of the tectonothermal evolution of this southern zone of the Iberian Massif[...]texto impreso

Sánchez-Donoso, Ramón ; Martín Duque, José Francisco ; Crespo Feo, Elena ; Higueras, Pablo L. | Springer | 2019-03The research on tailings deposits regarding geomorphic approaches, aeolian activity and integrated physical–chemical dynamics and instability is almost inexistent. This work performs such analysis at the San Quintín Mine site, located on the Alc[...]texto impreso
García Guinea, Javier ; Sánchez Muñoz, Luis ; Torno, J.L. ; Crespo Feo, Elena ; Ruiz Pérez, Javier ; Martín Herrero, Álvaro Ignacio ; Cremades Rodríguez, Ana Isabel | American Institute of Physics | 2009This paper mainly focuses on the spatial distribution of plagioclase phases observed by Raman and spectra cathodoluminescence (CL) emission of in the Villalbeto de la Peña meteorite. Initially, we collected fragments countryside to determine the[...]texto impreso
