Evolución geomorfológica de la Cuenca de Caravaca (Murcia): El resultado de un cambio en la red de drenaje durante el Pleistoceno medio

Abstract

The Caravaca basin, which is located at North of the Cadiz-AHcante Fault (Betic Cordillera), shows an Important tectonic activity during the Pliocene and Quaternary epochs■ Two zones, the North (Árgos River basin) and the South (Quipar River basin), with different geological and geomorphological behavior can be differentiated. The most important geomorphologic units are briefly described and the evolution of the fluvial network Is analyzed, the available data suggest the connection between both zones and the existence of a NW-SE fldvlal network; until Middle Pleistocene Times. During this period, tectonic movements provoked the desconnectlon of the drainage and afterwards the capturé of Argos River (North Zone) by an extern drainage, which has given rise to the strong dissection of this sector
