Chronology

In these uncertain times... we need better statistics.
  • Carling Hay and JC Creveling showed how an ensemble of different, plausible chronologies can be quantitatively assembled in matching chemostratigraphic variaitons. They used this approach to evaluate published chronologies of the Cambrian and to propose hundreds of new ones (2019).
  • Cristi Proistosescu developed a framework to better understand when orbital tuning should help improve the accuracy of a chronology (2012).
  • Another topic is how time uncertainty affects spectral analysis or marine proxy records (2004) and Martian polar layer deposits (2009). Basically, time errors smear the energy in spectral peaks across frequency. Andy Rhines showed, however, that timing errors do not much affect estimates of power-law distributions (2011).
