Geochronology is the study of time and its relationship to Earth's history. This site supplies a thorough introduction to geochronology, including popular methods used and some geologic applications of the results. Specific topics include superposition, biostratigraphy, radiometric dating, thermoluminescence, paleomagnetism, the fossil record, and extinctions. Additionally, the site supplies a summary of each geologic Era.
