Phrase: Ashfield Shale | Statement: [Wianamatta Group, stratigraphicSuperunitOf, Ashfield Shale]

Target entity: Ashfield Shale
Context triple: [Wianamatta Group, stratigraphicSuperunitOf, Ashfield Shale]

• A. Graneros Shale
  Graneros Shale is a Cretaceous-age marine shale formation in the central United States, notable for recording the early transgression of the Western Interior Seaway and for its fossil-rich, fine-grained sediments.
• B. Ninnescah Shale
  Ninnescah Shale is a geologic rock unit known for its shale deposits, typically associated with Permian-age sedimentary sequences in the central United States.
• C. Marcellus Shale
  Marcellus Shale is a vast natural gas–rich sedimentary rock formation underlying much of the Appalachian Basin in the eastern United States, notably Pennsylvania, West Virginia, Ohio, and New York.
• D. Curtis Formation
  The Curtis Formation is a Middle Jurassic geologic unit in the western United States, characterized mainly by marine sandstones and siltstones that record shallow sea environments.
• E. Carbondale Formation
  The Carbondale Formation is a Pennsylvanian-age rock unit in the Illinois Basin renowned for its rich coal beds and exceptionally preserved fossil assemblages, including those of the Mazon Creek area.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
