RT Journal Article T1 Datación de yacimientos paleontológicos de la cuenca de Guadix-Baza (sector de Cúllar-Baza, Granada, España) y primera estimación de la edad de la apertura de la cuenca mediante el método de racemización de aminoácidos T1 Dating of Guadix-Baza basin (Cúllar-Baza area, Granada, Spain) palaeontological sites and first estimation of the age of the basin opening based on the aminoacid racemization method A1 Ortiz, José Eugenio A1 Torres, Trinidad de A1 Llamas, F. J. A1 Canoira, L. A1 García Alonso, P. A1 García de la Morena, M. A. A1 Lucini, M. AB New amino acid racemization dating data from four Guadix-Baza basin (Cullar-Baza area) localities are presented. The former mathematical algorithms were improved to new ones based oh palaeomagnetical data from the basin.Dallo/isoleucine and D/L leucine racemization ratios were employed because they show the highest reliability for old sites dating. The palaeontological localities: Vehta Micena, Huescar-i, Cullar Baza-1 and Fuente Amarga-1 were dated as weli as a fluvial terrace linked to the beginingof the opening of the basin at the end of Middle Pleistocene times. For dating analysis, Ostracoda, using their equivalent ratios, and Gastropoda shells have been used PB Sociedad Geológica de España YR 1999 FD 1999 LK http://hdl.handle.net/10272/9854 UL http://hdl.handle.net/10272/9854 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
