Stratigraphic architecture of a Santonian mixed siliciclastic-carbonate succession (Catalonian Pyrenees, Spain)

摘要

At Collades de Bastus, Catalonian Pyrences, a Santonian mixed siliciclastic-carbonate succession indicates two proximal-distal gradients, and records two styles of stratigraphical development upon relative sea-level change. The succession consists of four small-scale sequences (5.1 to 5.4) within the highstand systems tract of the. “Valicarca-5” depositional sequence of Simo (1993), and is topped by a drowning sequence (small-scale sequence 5.5).
