Reconstructing past climates and earth system responses to climate and environmental change relies heavily on precise and accurate chronologies.
Radiocarbon dating continues to play a vital role in providing chronological control over the last 50,000 years, but advances in recent years on a range of other geochronological techniques that are applicable to the Quaternary have made a much wider diversity of methods available.

In this session, applications are particularly welcome that aim to (1) reduce, quantify and express dating uncertainties in any dating method, including high-resolution radiocarbon approaches, (2) use established geochronological methods to answer new questions, (3) use new methods to address longstanding issues, or (4) combine different chronometric techniques for improved results. Applications may aim to understand long term landscape evolution, provide rates of geomorphological processes, or provide chronologies for records of climate change.


Invited Presentations will be given by:

William G. Thompson from Woods Hole Oceanographic Institution on the state of the art in U/Th dating of corals 

and

Darren Mark from the NERC Argon Isotope Facility at the Scottish Universities Environment Research Centre on Ar/Ar dating of tephra associated with a site in Mexico where evidence for the earliest human occupation of the Americas has been proposed.
