Summary: Sedimentary and micropaleontological features of Cretaceous formations in the Betic Seaway have been examined. In the External Zone of the Betic Cordillera (Southern Spain) planktic and benthic foraminiferal assemblages were studied to establish a biostratigraphic framework and to provide estimates of paleo-waterdepth. Further environmental interpretations are based on the analysis of clay minerals, sedimentary petrography and organic geochemistry. We suggest the existence of several subbasins with differing subsidence histories created by transform tectonics along the axis of the Betic Seaway. A comparison with mid-Cretaceous sequences of adjacent DSDP/ODP holes indicates that the general paleoceanographic conditions within the seaway were similar to the North Atlantic. Our results are integrated in a paleogeographic reconstruction for the Western Mediterranean during the late Albian.
