Ouarkziz, Algeria

36. Ouarkziz, Algeria

This structure is situated in sedimentary rocks in the rocky desert of northwest Algeria. It displays a well-defined ring that is partly open to the south. The impact origin is suggested from the occurrence of planar deformation features within rocks returned 30 years ago from the only geologic expedition ever to visit the structure.
