Orientations of folds and small faults were measured in Turonian and Senonian rocks along the western limb of the Ramallah monocline in Israel, one of the structures comprising the Syrian Arc fold belt (SAFB). The minority of the folds, aligned NNE–SSW, are compatible with the WNW–ESE shortening trend of the SAFB, whereas the majority of them, aligned ENE–WSW, are not compatible with this shortening trend. Kinematic analysis of faults’ attitude indicates NNW–SSE shortening and ENE–WSW extension in accordance with the shortening of the majority of folds. Based on the folds trends, scale, and geometry, as well as the associated fault kinematics, we conclude that the folding mechanism is tectonic shortening and not intraformational folding due to landsliding or collapse owing to karst activity as previously postulated. We propose that a minority of the folds, compatible with the major trend of the Ramallah monocline, are parasitic small folds within the SAFB. The majority of the folds, which are not compatible with the SAFB, were formed owing to NNW–SSE shortening that has been associated with Miocene to Recent movement along the Dead Sea Transform.

Evolution of the Levant Margin and Western Arabia Platform since the Mesozoic
This volume combines original data in various fields from the offshore Levant Basin and adjacent continental slopes and platforms. The first group of papers document the tectonic structures and sedimentological patterns associated with the development of the Levant Basin. They identify the successive rifting events from the Late Palaeozoic to the Early Cretaceous, followed by a moderate tectonic activity. The contribution of external factors like global sea-level and climate changes to the sedimentation processes during the Mid-Cretaceous is discussed in the second set of papers. The final group presents new kinematics and age constraints on the Late Cretaceous to Neogene tectonic phases and discusses the relationship of the structures with the closure of the Neo-Tethys and separation of the Arabia plate. This collection of research papers demonstrates new concepts on the opening and crustal thinning of the Levant Basin and gives updated interpretations of the latter tectonic structures of the Levant.
