Sumario:The Carboniferous outcrops in the Central Priorat (Fig. V, Catalan Coastal Range, record a turbidite succession ranging from Tournaisian to a possible Westphalian, in which three allogroups can be recognized. From base to top these groups are named Torroja, Bassetes and Poboleda. The Torroja group records the inversion stages of a compressive basin by a basal succession of south margin derived megabreccias, underlying a fine-grained turbidite slope-delta wedge evolving from NW. The Bassetes and Poboleda groups have a terrigenous character and have been divided in composite depositional sequences (Fig.2), recording different large channel-levee systems, evolving upward to slope-delta wedges. Gravel and sand-rich turbidites are NW derived and are located in relatively proximal positions of large turbidite systems. Composite depositional sequences record uplift-denudation cycles. SEDEX deposits are placed into the Bassetes group
