Phrase: Panthalassa Ocean margins | Statement: [Toarcian Oceanic Anoxic Event, hasGlobalExtent, Panthalassa Ocean margins]

Target entity: Panthalassa Ocean margins
Context triple: [Toarcian Oceanic Anoxic Event, hasGlobalExtent, Panthalassa Ocean margins]

• A. Eurasian continental margin
  The Eurasian continental margin is the submerged edge of the Eurasian tectonic plate, extending from its coastal shelves into the deep Arctic and Atlantic oceans and encompassing features such as the Chukchi Plateau.
• B. North Atlantic plate boundary system
  The North Atlantic plate boundary system is the complex tectonic zone where the North American, Eurasian, and related plates interact through mid-ocean ridges, fracture zones, and transform faults across the North Atlantic Ocean.
• C. East Pacific tectonic system
  The East Pacific tectonic system is a major geological region in the eastern Pacific Ocean characterized by active seafloor spreading, transform faults, and subduction zones that shape the surrounding oceanic plates and continental margins.
• D. North Atlantic fracture zone system
  The North Atlantic fracture zone system is a network of major oceanic crustal faults and offsets that segment the Mid-Atlantic Ridge and shape the seafloor topography of the North Atlantic Ocean.
• E. passive margin of Gondwana
  The passive margin of Gondwana was the long, tectonically quiet continental edge of the ancient supercontinent Gondwana, where thick sedimentary sequences accumulated and from which various microcontinents, such as Avalonia, later rifted away.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Panthalassa Ocean margins
Triple: [Toarcian Oceanic Anoxic Event, hasGlobalExtent, Panthalassa Ocean margins]

The Panthalassa Ocean margins were the extensive continental and volcanic arc boundaries of the vast Panthalassa superocean that surrounded the supercontinent Pangaea during much of the Mesozoic Era.
