Potassium-argon courting is a method that enables us to calculate the age of a rock, or how long ago it was formed, by measuring the ratio of radioactive argon to radioactive potassium inside it. Using the precept of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the 2 species must have existed during the same time frame (Figure 4). If the same index fossil is discovered in numerous areas, the strata in every area have been probably deposited at the similar time. Thus, the precept of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites throughout giant discontinuous areas.

Dating options corresponding to moraines allows the timing of significant stabilizations of outlet glaciers to be characterised. Chronologies should be constructed with adherence to quality assurance protocols, which additionally enable tools for the analysis and comparison of latest datasets to legacy knowledge. Outliers can be assessed using a range of instruments, together with Bayesian age modelling, which allows chronologies to be constructed from different courting strategies if depositional contexts are sufficiently understood to construct a ‘prior’ model. These methods collectively may be applied to derive extremely assured mean age estimates for glacial landforms.
