In their recent article, Abed et al. (Arab J Geosci DOI: 10.1007/s12517-014-1427-6, 2014) critically address the impact nature of the ∼6 km Jebel Waqf as Suwwan impact structure in eastern Jordan. We here comment on several statements the authors make in their study. Altogether, the presence of a very typical impact crater structure and morphology, well-developed shatter cones in situ, and planar fractures in combination with feather features and transmission electron microscopy (TEM)-verified planar deformation features (PDF) in quartz collectively fulfills several shock metamorphic criteria that convincingly characterize the Jebel Waqf as Suwwan structure as a complex meteorite impact structure well accessible for geologic study.
