Exempel på hur man kan använda CHEMOSTRATIGRAPHIC i en mening

• Second, regionally or globally correlatable chemostratigraphic signals can be found in rocks whose formation time is well-constrained by radionuclide dating of the strata themselves or by strata easily correlated with them, such as a volcanic suite that interrupts nearby strata.
• It satisfies all the geological and biostratigraphic requirements for a GSSP, is readily accessible, and includes chemostratigraphic, palaeogeographic, facies-relationship, and sequence-stratigraphic information.
• Due to heating, possibly from an intrusive dike, the stratotype is unfit for dating by magnetic analysis, but this lack is compensated by the diversity of chemostratigraphic and biostratigraphic options.
• Formerly considered Barremian, the latest chemostratigraphic and geochronological studies conclude that the Yellow Member is older, with deposition occurring Berriasian–Valanginian stages.
