Ambientes sedimentarios y secuencias en la Fm. Higueruelas (Jurásico Superior) en la Cordillera Ibérica Septentrional
(Sociedad Geológica de España, 2003)Fades analysis carried out in the Higueruelas Fm. (Tithonian, latest Jurassic) in the northern Iberian Chain (Mezalocha, Aguilon and Fuendetodos outcrops), has resulted in the identification of 14 fades. These fades were ... -
Rasgos hidrogeoquímicos de las aguas termales en los acuíferos carbonatados del Bajo Andarax (Almería)
(Sociedad Geológica de España, 2003)The carbonate aquifers of the Lower Andarax is a significant geothermal anomaly, as evidenced by the high temperature of the spring waters (22 - 40 °C). The most saline waters (2000 - 3000 mg.L1) correspond to the Deep ... -
