[[File:BP crater x5.jpg|thumb|200px|right|Oblique [[Landsat]] image of BP crater draped over digital elevation model (x5 vertical exaggeration); screen capture from [[NASA World Wind]]]]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.<ref>{{cite Earth Impact DB | name = BP | linkname = bpstructure | accessdate = 2009-08-12}}</ref>

French ''et al.'' state that the BP Structure and the larger [[Oasis crater]], about {{cvt|88|km}} to the south, were probably simultaneous impacts.<ref>BEVAN M. FRENCH, JAMES R. UNDERWOOD, EDWARD P.
