Análisis preliminar de la ciclicidad en la sección continental FP-1 (Plioceno-Pleistoceno, Cuenca de Guadix, Cordillera Bética)
A detailed cyclostratigraphic and paleomagnetic study was carried out on the cyclically bedded succession of Pliocene and Pleistocene floodplain deposits FP-1(Guadix Basin, Spain). Sedimentary cycles are recognised at least on two different scales. The hierarchy is interpreted to represent periodic...

| Sumario: | A detailed cyclostratigraphic and paleomagnetic study was carried out on the cyclically bedded succession of Pliocene and Pleistocene floodplain deposits FP-1(Guadix Basin, Spain). Sedimentary cycles are recognised at least on two different scales. The hierarchy is interpreted to represent periodic alluvial fan expansion over the floodplain area. The cyclicity is affected by a change in the sedimentary conditions aged 1.778 Ma, coinciding with the boundary between the two most modern genetic units of the Guadix Basin continental filling (unit V and unit VI). The aim of this work is to discuss the possibility of relating the cyclicity of the sediments from the FP-1 section with the astronomical cycles of Milankovitch |
