Phrase: Tyrrhenian back-arc basin system | Statement: [Marsili Basin, partOf, Tyrrhenian back-arc basin system]

Target entity: Tyrrhenian back-arc basin system
Context triple: [Marsili Basin, partOf, Tyrrhenian back-arc basin system]

• A. Aegean back-arc extension
  Aegean back-arc extension is a tectonic process in the Aegean region characterized by crustal stretching and thinning behind the Hellenic subduction zone, leading to widespread normal faulting and basin formation.
• B. Andean back-arc basins
  Andean back-arc basins are sedimentary basins that formed behind the Andean volcanic arc due to tectonic extension and subsidence related to subduction along the western margin of South America.
• C. Hellenic subduction system
  The Hellenic subduction system is a major convergent plate boundary in the eastern Mediterranean where the African Plate is being subducted beneath the Aegean microplate, creating deep-sea trenches, intense seismicity, and active volcanism.
• D. 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.
• E. Ryukyu back-arc basin
  The Ryukyu back-arc basin is a seafloor spreading region behind the Ryukyu island arc, formed by the subduction of the Philippine Sea Plate beneath the Eurasian Plate and characterized by active tectonism and volcanism.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
