Resumen
[ES] Este estudio pretende determinar la influencia de los factores climáticos, tectónicos y geomorfológicos que determinan la formación de sedimentos lacustres ricos en restos fósiles, a través de diversas técnicas y métodos de caracterización y análisis mineral y geoquímico. Se estudiaron sedimentos endorreicos de la cuenca de Guadix-Baza, así como sedimentos fluviales de una terraza perteneciente a la red de drenaje actual de la cuenca, que forma parte de la cuenca hidrográfica del río Guadiana Menor. Las edades de los dos niveles son muy diferentes, por una parte las muestras BLGl y BLG2 pertenecen al pleistoceno inferior, y por otro lado, entre el pleistoceno superior y el holoceno, corresponden a las muestras LGl hasta LG6. Entre otros objetivos se pretende comparar dichos niveles, aparentemente similares a visu para ver sus relaciones ambientales.

Endorheic sediments of the Guadix-Baza basin were studied, as well as in fluvial sediments of a terrace belonging to the current drainage network of the basin, which forms part of the watershed of the Guadiana Menor river. The ages of the two leve Is are very different, on the one hand samples BLGl and BLG2 belong to the lower pleistocene, and on the other hand, between the upper pleistocene and the holocene, correspond to samples LGl to LG6. Among other objectives, it pretend to compare such levels, apparently similar to visu to see their environmental relationships.
