Amino acid geochronology
Elsevier eBooks(2023)
摘要
Amino acid geochronology is a well-established dating technique used in a wide range of Quaternary sciences. The primary geochronometer is the extent of racemization of amino acids preserved in a variety of organic remains. As a relative-dating tool, it is used to distinguish and correlate units, identify unconformities, and quantify the distribution of ages within fossil assemblages, among other applications. As a calibrated-dating method, it is used to estimate numerical ages by calibrating the rate of racemization against other dating techniques in a regional context. Where ages are known, the method can also be used for paleothermometry.
