RT Journal Article T1 Sondeos de investigación en un acuífero kárstico costero (Castell de Ferro, Granada) A1 Pulido Bosch, Antonio A1 Pulido Leboeuf, P. A1 Vallejos, Ángela A1 Calvache Quesada, María Luisa A1 Gisbert, Josep A1 Andreu Rodes, José Miguel A1 Sánchez Martos, Francisco A1 Molina, Luis AB Data from 4 investigation boreholes, drilled in the marbles of the Castell de Ferro aquifer and separated some 5 m each one from the next one, are discussed. Several karstic discontinuities are detected at different depths depending on which borehole they are in. Flowmeter measurements show the presence of vertical flows at different positions. An electrical conductivity anomaly is detected and interpreted as a result of the drilling method PB Sociedad Geológica de España YR 1998 FD 1998 LK http://hdl.handle.net/10272/10199 UL http://hdl.handle.net/10272/10199 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
