[Aqualist] IGC 2012 - Session 19.2 Dating our recent past - analytical methods in Quaternary geochronology and paleoclimatology - abstracts close Feb 17th

[Jian-xin Zhao]

Dear Quaternary geochronologists, geochemists and palaeoclimatologists,

We would like to call your attention to a session on "Dating our recent 
past - analytical methods in Quaternary geochronology and paleoclimatology" 
that River Shen, Gangjian Wei and I are co-convening at the upcoming 34th 
International Geological Congress (IGC) in Brisbane, Australia, 5-10th 
August 2012.

You can submit abstracts (by 17th Feb) here:

19.2 Dating our recent past - analytical methods in Quaternary geochronology 
and paleoclimatology

Increased worldwide concerns with recent global climate and environmental 
changes have stimulated considerable interest in Quaternary research - the 
study of the Earth's environment over the last 2 million years. 
Technological advances in Quaternary geochronology and geochemical and 
isotope proxy-based palaeoclimate and palaeoenvironmental reconstruction 
over the last few decades have also contributed to revolutionizing 
Quaternary research. The Quaternary Era lends itself to the largest number 
of dating methods, including long-lived and short-lived radioisotopes (e.g., 
radiocarbon, K-Ar and 40Ar/39Ar, U-series, cosmogenic nuclides), radiation 
exposure dating (e.g., TL, OSL, ESR, fission-track dating), relative dating 
(e.g., AAR), as well as dating using annual banded records (e.g., 
dendrochronology). In addition to chronometric techniques, recent advances 
have been made in the use of various geochemical and isotope proxies for 
palaeoclimate and palaeoenvironmental reconstructions, such as 
carbon-oxygen-sulfide isotopes, clumped isotopes, boron isotopes, etc. for 
the studies of palaeotemperature, precipitation, seawater alkalinity and 
recent acidification and other environmental parameters. The development of 
various techniques has focused on improving the analytical precision and 
accuracy of determinations, on improving the sensitivity and reducing the 
size of sample required for measurements, on increasing sample throughput, 
on high-resolution in situ analysis, and on developing new tools. This 
Symposium is open to all Quaternary chronometric and 
geochemical-proxy-reconstruction techniques, as well as the innovative 
applications of such techniques to novel questions.

Looking forward to your participation.

Best regards

Jian-xin Zhao
