Target entity: international stratotype for the Permian–Triassic boundary
Context triple: [Meishan section, recognizedAs, international stratotype for the Permian–Triassic boundary]
  • A. 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.
  • B. Global Boundary Stratotype Section and Point chosen
    The Global Boundary Stratotype Section and Point (GSSP) is an internationally agreed reference point in a specific rock sequence that precisely defines the lower boundary of a stage or age in the geologic time scale.
  • C. Lomagundi–Jatuli carbon isotope excursion
    The Lomagundi–Jatuli carbon isotope excursion was a major global perturbation in the carbon cycle during the Paleoproterozoic, marked by unusually high carbon isotope ratios that suggest prolonged burial of organic carbon and significant changes in Earth’s atmosphere and oceans.
  • D. Global Boundary Stratotype Section and Point at Klonk, Czech Republic
    The Global Boundary Stratotype Section and Point at Klonk in the Czech Republic is a formally designated geological reference site that marks the internationally agreed base of the Devonian System and serves as a key standard for correlating Early Devonian rock strata worldwide.
  • E. International Chronostratigraphic Chart
    The International Chronostratigraphic Chart is the globally recognized standard timeline used by geologists to define and correlate the divisions of Earth’s geological history.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
