RT Journal Article T1 Composición isotópica de las aguas de la Unidad Hidrogeológica Yunquera-Nieves (Provincia de Málaga) T1 Isotopic composition of the waters in the Hydrogeological Unit Yunquera-Nieves (Province of Malaga) A1 Liñán Baena, Cristina A1 Jiménez de Cisneros, C. A1 Caballero Mesa, E. A1 Carrasco Cantos, Francisco A1 Andreo Navarro, Bartolomé AB The isotopic composition of the waters sampled in the Hydrogeological Unit Yunquera-Nieves are from Mediterranean and Atlantic origin. The lsO and 2H contents define a local meteoric water line with lower slope than mundial meteoric water line, because of the evaporation process. The mineralization and isotopic composition of the waters decreases with the altitude, which allow us delimite the recharge surface of the main springs of the Unit. The mineralization and the isotopic composition of rainwater vary inversely to the amount of precipitation. The springwaters deplete their mineralization and isotopic content in response to the outflow increase because of the important winter precipitations. Anyway, the responses are quick, which probe the karstic behaviour of the springs PB Sociedad Geológica de España YR 1998 FD 1998 LK http://hdl.handle.net/10272/10158 UL http://hdl.handle.net/10272/10158 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
