The BP Structure, also known as Gebel Dalma, is an exposed impact crater in Libya. It is so called because it was identified by a BP (then British Petroleum) geological survey team.[1]

French et al. state that the BP Structure and the larger Oasis crater, about 88 km (55 mi) to the south, were probably simultaneous impacts.[2] Both impacts deform the Nubian Sandstone of early Cretaceous age.
