High-frequency cycles in the upper Aptian carbonates of the Organyà basin, NE spain

Abstract

High-frequency cycles in Upper Aptian carbonates have been studied on the carbonate ramp of Organya (southeastern Pyrenees). The depositional area comprises a shallow marine to deeper marine transect. A detailed facies model is developed subdividing the transect into an inner ramp area (above fairweather wave base), a mid-ramp area (between fairweather wave base and storm wave base) and an outer ramp area (below storm wave base).
