Title Amino Acid Geochronology: Recent Perspectives
CommissionSACCOM
Description

The racemization of amino acids preserved in Quaternary fossils provides geochronological information applicable to a wide range of stratigraphic problems, depositional environments, and time scales. Recent advancements in biomolecular techniques and greater understanding of protein degradation show promise for improving amino acid geochronology, while reduced sample size requirements have opened new avenues of investigations. This session will bring together specialists in amino acid geochronology and scientists who have used amino acid data to provide timescales for solving a range of geological, archaeological, and climatological problems. The goal is to assemble a volume of papers highlighting recent applications and advances in amino acid geochronology.
