==Numerical ages==

Rate-dependent analyses such as subsidence analysis, deposition rate, and [[maturation]] modeling require age-depth pairs as input data. Numerical ages are critical to accurate analyses and ideally should be based on high-resolution biostratigraphic control calibrated to a standard [http://www.britannica.com/EBchecked/topic/229486/geochronology geochronology], such as Harland et al.<ref name=ch17r44>Harland, W., B., Armstrong, R., L., Cox, A., V., Craig, L., E., Smith, A., G., Smith, D., G., 1990, A Geologic Time Scale—Revised Edition: Cambridge, Cambridge University Press, 263 p.</ref> Berggren et al.<ref name=ch17r15>Berggren, W., A., Kent, D., V., Swisher, C., Aubry, M.-P., 1995, A revised Cenozoic geochronology and chronostratigraphy, in Berggren, W., A., Kent, D., V., Aubry, M.-P., Hardenbol, J., eds., Geochronology, Time Scales, and Global Stratigraphic Correlation: Society for Sedimentary Geology (SEPM) Special Publication 54, p. 127–208.</ref> or Gradstein et al.<ref name=ch17r42>Gradstein, F., M., Agterberg, F., P., Ogg, J., G., Hardenbol, J., Van Veen, P., Thierry, J., Huang, Z., 1995, A Triassic, Jurassic, and Cretaceous time scale, in Berggren, W., A., Kent, D., V., Aubry, M.-P., Hardenbol, J., eds., Geochronology, Time Scales, and Global Stratigraphic Correlation: Society for Sedimentary Geology (SEPM) Special Publication 54, p. 93–125.</ref>
