Triple

Target entity: North Sea rift system
Context triple: [Witch Ground Graben, partOf, North Sea rift system]

• A. North Sea rift system chosen
  The North Sea rift system is a major geological rift complex underlying the North Sea, formed by extensive Mesozoic and Cenozoic crustal extension that created numerous sedimentary basins important for hydrocarbon resources.
• B. Gotland Basin
  Gotland Basin is a deep, central sub-basin of the Baltic Sea known for its significant role in the region’s water circulation, stratification, and marine ecology.
• C. East Greenland Rift System
  The East Greenland Rift System is a major geological rift zone along Greenland’s eastern margin that records the stretching and breakup of the crust during the opening of the North Atlantic Ocean.
• D. European Cenozoic Rift System
  The European Cenozoic Rift System is a major network of tectonic rift valleys and basins that formed across western and central Europe during the Cenozoic era, significantly shaping the region’s topography and volcanic activity.
• E. Moine Thrust Belt
  The Moine Thrust Belt is a major geological structure in northwest Scotland where ancient rocks were pushed westward over younger rocks, forming one of the world’s classic examples of a thrust fault zone.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
