Getting the age of a geological event or the speed of a geological process requires acquiring indirect data, making some assumptions about the studied process and the data we have, and usually making a lot of calculations. These assumptions always include descriptions of geological processes using mathematical concepts and language, i.e., models. Therefore, any geochronological age is the result of a “model”.
Cosmonuclide dating requires a wide variety of data analyses. Most of these analyses include mathematical models (e.g. the formulas that describe the production of cosmogenic isotopes). The following flow chart describes many of the calculations we do when working with cosmogenic data. The chart also contains links to publications, manuals, online tools, databases, and applications related to cosmo-data analysis.
