RT Journal Article T1 ¿Registro de un paleoincendio en el límite Plioceno-Pleistoceno de la cuenca de Guadix-Baza (Granada, España)? T1 A wild-fíre record at the Pliocene-Pleistocene boundary in the Guadix-Baza Basin (Granada, Spain)? A1 Ortiz, José Eugenio A1 Torres, Trinidad de A1 Valle Hernández, María A1 Badal, E. A1 Llamas, F. J. A1 Cortés, A. A1 Vela, A. AB This paper deals with the organic geochemistry of a "lignite" bed at the bottom of the Guadix-Baza composite stratotype section, just below the end of the Olduvai Chron. The results of the organic matter analysis (low H/C ratio and predominance of even n-alkanes) together with the lack of pollen and micromammal remains as well as the abundance of charcoal particles, suggest the development of the first wild-fire in the Mediterranean realm, which affected the catchment area of the alluvial fan that fed the Cortes de Baza area PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8955 UL http://hdl.handle.net/10272/8955 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 15 jun 2026
