Potassium-argon courting is a technique that permits us to calculate the age of a rock, or how long ago it was fashioned, by measuring the ratio of radioactive argon to radioactive potassium within it. Using the precept of faunal succession, if an unidentified fossil is present in the same rock layer as an index fossil, the two species must have existed throughout the same time period (Figure 4). If the identical index fossil is discovered in several areas, the strata in every area were likely deposited at the identical time. Thus, the precept of faunal succession makes it attainable to discover out the relative age of unknown fossils and correlate fossil sites across massive discontinuous areas.

Dating features corresponding to moraines permits the timing of serious stabilizations of outlet glaciers to be characterized. Chronologies must be constructed with adherence to high quality assurance protocols, which also allow tools for the evaluation and comparability of recent datasets to legacy information. Outliers could be assessed utilizing a range of tools, including Bayesian age modelling, which allows chronologies to be constructed from totally different courting methods if depositional contexts are sufficiently understood to build a ‘prior’ model. These methods together can be utilized to derive extremely confident mean age estimates for glacial landforms.
