Our field examination of the structure and subsequent petrographic study of the critical rock types failed to reveal a single feature attributable to shock processes. We, therefore, dismiss an impact origin for this structure. It must, instead, be endogenic. The same conclusion applies to the much smaller, associated, Semsiyat Dome. This content is PDF only.
