Carbonate aquifers threatened by contamination of hazardous anthropic activities: Challenges
Vadillo-Pérez, Iñaki
; Ojeda, Lucía (Elsevier, 2022)
This review focuses on the challenges that need to be addressed to increase knowledge on the distribution, transport and biogeochemical reactions of contaminants in carbonate media. In order to do so, it has been necessary ... -

Coupling air temperature records and gravimetric data to interpret ventilation patterns in a Mediterranean karstic system (Nerja-Pintada caves, southern Spain)
(Elsevier, 2020)Microclimate and geophysical studies are commonly applied to the characterization of karst systems although they are usually used separately. The main purpose of this manuscript is to show how the analysis of the data from ... -
Discriminating organic carbon from endokarstic moonmilk-type deposits by LIBS. The case of a natural carbonated Martian analogue
Delgado-Pérez, Tomás; García-Gómez, Laura; Fortes-Román, Francisco Javier; Cabalín-Robles, Luisa María; Liñán-Baena, Cristina; Vadillo-Pérez, Iñaki; Jiménez-Gavilán, Pablo; Ojeda, Lucía; Laserna-Vázquez, José Javier[et al.] (Elsevier, 2024-01-06)
Moonmilk-type deposits exemplify carbonated Martian analogues existing in the subsurface of Earth, an endokarstic speleothem with a possible biochemical origin composed principally by carbonates, mainly huntite and dolomite. ... -
Methane concentration and isotopic composition (d13C-CH4) in the Nerja Cave system (South Spain)
Vadillo-Pérez, Iñaki; Etiope, Giuseppe; Benavente Herrera, José; Ojeda, Lucía; Liñán-Baena, Cristina; Carrasco-Cantos, Francisco[et al.] (2016-04-26)
Air in underground caves often has methane (CH4) concentrations below the atmospheric level, due to methanotrophic or other unkown CH4 consuming processes. Caves are thus considered a potential sink for atmospheric methane. ... -
