Abstract

El corte del Río de Gor muestra la evolución lateral de los materiales de la Fm. Guadix (fluvial) a la Fm. Gorafe-Huelago (lacustre). Desde el borde de la cuenca hacia el interior (en 6 km) se reconocen, en los materiales pliocenos, los siguientes medios sedimentarios yuxtapuestos: A. Abanico aluvial medio. B. Abanico aluvial medio. C. Ríos trenzados (braided). D. Meandriforme proximal. E. Meandriforme distal. F. Llanura lutítica. G. Medio lacustre.

The cross-section in the Gor river shows the lateral evolution of the Guadix (fluvial) towards the Gorafe-Huelago (lacustrine) formations. In the Pliocene materials, we have recognised the following sedimentar~ en vironments, from the border to the center of the basin: A. Inner alluvial fan. B. Middle alluvial fan. C. Braided fluvial system. D. Proximal meandering fluvial system. E. Dista1 meandering fluvial system. F. Muddy plain. G. Lacustrine.

Este trabajo ha sido realizado en el seno del proyecto de investigación "Análisis sedimentológico, mineralógico y evolución tectosedimentaria de las depresiones béticas orientales" financiado por la C.A.I.C.Y.T. y el C.S.I.C. organismos a quienes se agradece su ayuda.

Queremos agradecer la colaboración de C. Jiménez de Cisneros y J. M. Castro.
