(Sociedad Geológica de España, 2016)“Campiña” playa-lakes, originated in relation to clay-evaporite materials of Depression of the Guadalquivir, are characterized by their temporary hydroperiod and saline waters. Among these, it highlights the lacustrine ... -
Distribución de los micromoluscos actuales de los Ojos de Añavieja (Soria, España)
(Sociedad Geológica de España, 2016)In this work, the recent micromollusc assemblages of the Añavieja springs have been studied, identifying one bivalve (Pisidium sp.) and 12 gastropod species, five of which are terrestrial (Cochlicella sp., Truncatellina ... -
Dolomita bacteriana en facies carbonato-yesíferas de lagos efímeros (Formación Deza, Eoceno superior, Cuenca de Almazán)
(Sociedad Geológica de España, 2016)The lower sequence of the Deza Formation represents an ephemeral carbonate lacustrine environment revealed by the presence of limnic fossil and evidence of dry periods marked by the presence of numerous carbonate pseudomorphs, ... -

Estimación de parámetros hidrogeológicos en los acuíferos costeros del Bajo Guadalhorce (Málaga) mediante el análisis de la influencia de las mareas
(Sociedad Geológica de España, 2016)By the use of continuous data recording on two points of the Bajo Guadalhorce coastal sector (Malaga province, southern Spain), located at 626 m and 985 m inland, it has been possible to verify a clear influence of tidal ... -
Estimación geoestadística del contenido en manganeso en suelos y su relación con las aguas subterráneas en España
(Sociedad Geológica de España, 2016)Metal content in groundwater is a problem intensely studied by different researchers worldwide. High concentrations of these elements are related to geogenic sources besides of anthropogenic activities. In this work, a ... -
Evolución hidroquímica de las aguas superficiales en los tramos alto y medio del río Andarax (Almería)
(Sociedad Geológica de España, 2016)The Andarax river includes every kind of flow type along its course: perennial, intermittent and ephemeral. This diversity of flow, along with the variable lithology of the area and the influence of groundwater influences ... -
