Target entity: Mediterranean back-arc domain
Context triple: [Tyrrhenian back-arc basin system, partOf, Mediterranean back-arc domain]
  • A. Tyrrhenian back-arc basin system
    The Tyrrhenian back-arc basin system is a tectonically active region in the western Mediterranean characterized by seafloor spreading, extensional processes, and associated volcanic activity behind the Apennine subduction zone.
  • B. 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.
  • C. Mediterranean Ridge accretionary complex
    The Mediterranean Ridge accretionary complex is a vast submarine geological structure in the eastern Mediterranean formed by the ongoing convergence and subduction of tectonic plates, resulting in intense deformation and sediment accumulation.
  • D. Cascadia back-arc region
    The Cascadia back-arc region is a tectonically active area east of the Cascadia subduction zone characterized by crustal extension, volcanism, and associated magmatic and geothermal activity.
  • E. Mediterranean volcanic province
    The Mediterranean volcanic province is a geologically active region surrounding the Mediterranean Sea, characterized by numerous volcanic arcs, islands, and complexes formed by complex plate interactions and subduction processes.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
