Abstract
Se estudian desde un punto de vista estratigráfico-sedimentológico los materiales de facies
Culm de un sector de la Faja Pirítica (Zona Sur-Portuguesa).
Se interpreta la existencia de dos dispositivos turbidíticos principales, uno de dirección WNWESE,
constituido por turbiditas tipo I YIII de Mutti (1985) y otro NE-SW con turbiditas 11 y 111.
La acción simultánea de ambos dispositivos queda de manifiesto por la existencia de ciclos de
facies de características mixtas allá donde se considera que coincidieron sus materiales (región de
Gibrale6n).
La sedimentación sincrónica de los dos sistemas turbidíticos principales sugiere un origen catastrofista
para el depósito de sus materiales.
This paper deals with the stratigraphy and sedimentology of the Culm facies in a sector of the Iberian Pyrite Belt (South-Portuguese Zone). In the studied area two main turbidite systems occur. The WNW-ESE one is made with turbidites of type I and III (Mutti, 1985), the other one, with a direction NE-SW, includes turbidites of type 11 and 111. The contemporary interrelation between the two main turbidite systems suggests a catastrophic way of deposition for this sediments. This Gibrale6n area is interpreted as the place where this interrelation occur, their facies cycles including intermediate characteristic of the two systems.
