-slip faults create important geologic structures where hydrocarbons may accumulate. Releasing bends and step-overs create transtensional zones often recognized as pull-apart basins... where organic sediments and reservoir sands accumulate. Restraining bends and step-overs create transpressional uplifts called pop-ups with folds and reverse faults that may trap... migrating hydrocarbons. Pull-apart basins filled with turbidites subsequently may be inverted into pop-ups as strike-slip continues along the major fault zones. The Neogene oblique...
