The Sakaka Sandstone, of reported Middle Cretaceous age, crops out primarily within the area of al Jawf, northwestern Saudi Arabia. The formation is mostly sandstone with some siltstone and shale. Detailed study of lithofacies suggests that the depositional environments of the Sakaka sediments changed from fluvial in the lower part to shoreline and shallow water in the uppermost part. Directional features in the sandstones show that the Sakaka sequence was deposited on top of the Sakaka (or Jawf) arch at a time when the arch was a positive feature. This arch may be part of a broad uplift extending from central Saudi Arabia (Ha'il arch) through al Jawf and southern Iraq (Rutbah high) to southern Turkey (Mardin high).
