RT Journal Article T1 El sistema aluvio-travertínico de Frailes (Cuenca Neógeno-Cuaternaria de Alcalá la Real, provincia de Jaén, Cordillera Bética) T1 The Frailes alluvial-travertine system (Alcalá la Real Neogene-Quaternary Basin, Jaén province, Betic Cordillera) A1 García García, Fernando A1 Nieto, Luis M. AB On study an alluvial-travertine complex system located near to Frailes village (Betic Cordillera, Jaén province).It is made up of two steps with their flat top located at 930 and 1026 m a.s.l. The lower one prograding toN130ºE is mainly formed by allochthonous travertine facies. The upper step consists of alluvial and travertinefacies. There are two detrital facies associations, characteristic of alluvial fan, and three carbonate faciesassociations consisting of allochthonous and bioconstructed travertine sediments, oncolite and stromatolitefacies. The carbonate facies associations were deposited in pool-dam-cascade sub-environments. Theprogradation of the upper step is to N210ºE PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8832 UL http://hdl.handle.net/10272/8832 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
