An introduction to the techniques used to study the history and ages of geological speciments. We begin with an overview of chronostratigraphy, covering principles of relative dating, way up indicators, and biostratigraphy. We then discuss geochronology, including a review of early attempts to determine the age of the Earth, the principles and assumptions of radiometric dating, and the radioisotopes most commonly used for dating. Finally, we discuss processes and mechanisms of fossilisation, and review some of the most important classes of index fossils. Recommended pre-listening is Episode 74: Minerals and Rocks, and Episode 77: Nuclear Physics.
