Sharland et al. (2001) define two tectonic mega-sequences on the Arabian Plate encompassing Late Cretaceous and Early Tertiary time—AP9 and AP10. These mega-sequences mark the transition of the Arabian Plate from a passive margin setting to a tectonically active margin located along its northeastern edge. Ophiolite obduction and the creation of a foredeep with rapid subsidence were key events. Despite the tectonically active nature of this interval of time, Sharland et al. (2001) recognize six plate-wide third-order sequences (K150, K160, K170, K180, Pg10, and Pg20) within the relevant preserved rock record, sequences that have been upheld in subsequent reviews of Arabian Plate sequence stratigraphy (e.g., Simmons et al., 2007). Figure 1 summarizes the depositional sequences present in mega-sequences AP9 and AP10 on the Arabian Plate and the generalized facies architecture.
