subcommission on Silurian stratigraphy

Target entity: subcommission on Silurian stratigraphy
Context triple: [International Commission on Stratigraphy, hasPart, subcommission on Silurian stratigraphy]

• A. The Silurian System, Founded on Geological Researches in the Counties of Salop, Hereford, Radnor, Montgomery, Caermarthen, Brecon, Pembroke, Monmouth, Gloucester, Worcester, and Stafford
  "The Silurian System" is a landmark 19th-century geological treatise by Roderick Murchison that established and described the Silurian period through detailed stratigraphic studies in parts of England and Wales.
• B. Commission on Tectonics and Structural Geology
  The Commission on Tectonics and Structural Geology is a specialized scientific body that promotes international research, collaboration, and standards in the study of Earth's tectonic processes and deformation structures.
• C. Global Boundary Stratotype Section and Point for base of Hettangian
  The Global Boundary Stratotype Section and Point for the base of the Hettangian is the internationally agreed geological reference point that marks the formal beginning of the Jurassic Period and the Mesozoic era’s post-Triassic recovery interval.
• D. Magnesian Limestone succession
  The Magnesian Limestone succession is a geological sequence of Permian-age dolomitic limestone formations that forms a distinctive belt across parts of northern and central England.
• E. Moine Supergroup
  The Moine Supergroup is a sequence of Neoproterozoic metamorphic rocks in the Scottish Highlands, notable for recording early tectonic events prior to the Caledonian orogeny.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity description: The Subcommission on Silurian Stratigraphy is an expert body of stratigraphers that establishes and refines the global geological time scale and stratigraphic standards for the Silurian Period.
