Abstract

The chemostratigraphic record for the mid-Cretaceous of the Arabian platform is well documented and records a period of large-scale perturbations in the in global carbon cycle. These records are however almost exclusively from platform and periplatform environments. This study seeks to enhance the current database by documenting and correlating the chemostratigraphic record from the platform margin to basin setting. This study documents the carbon and oxygen isotope stratigraphy from a series of Aptian-aged subsurface well sections located within the Bab basin. The well sections sampled penetrate moderately productive lime mud-rich reservoirs that originated during and after the Early Aptian oceanic anoxic event 1a (OAE 1a). One-foot samples were collected from cores for the analysis, and in some wells half-a-foot samples were collected. This high-resolution sampling will help to highlight minor excursions and anomalies that are lost in coarser sampling resolutions.
