Goldschmidt 2008 in honour of D. York

��, 14 �� 2008 10:12:02 GMT

Dear Colleagues

We would like to invite you to a session on high temperature thermochronology, tectonics and P-T-t paths at the Goldschmidt Conference in Vancouver Canada, 13^th to 18^th July 2008, in honour the work of Derek York who died last year. The abstract deadline is (March 1st).

The session is intended to bring together researchers using the latest techniques to understand the rates and timescales of crustal processes. A short description of the session appears below, and Chris Hall (U Michigan) will be giving a keynote talk.

The timescales of Earth's processes fascinated Derek York for nearly half a century after he joined a small group developing radioactive dating techniques in 1957 and developed a lifelong obsession with time and its measurement. Derek was interested in many aspects of the science of geochronology, in particular the rates and timescales of crustal processes, and he developed innovative techniques and approaches to high precision and high spatial resolution isotope dating. This session is intended to highlight recent advances and in theory and applications of radiogenic isotope geochronology to unravelling the relationship between different magmatic, tectonic and metamorphic processes which are sensitive to thermal histories characteristic of deep or mid-crustal processes, or magmatic or other high-temperature processes. We particularly encourage presentations related to the manner in which deep crustal processes control the rates and timescales of surface processes including mountain building, and in addition the manner in which surface processes such as precipitation and rates of chemical and physical weathering can control the rates of deeper crustal processes.

For more information on the conference which includes several related thermochronology sessions go the conference website.

http://www.goldschmidt2008.org/index
All abstracts will be published in Geochimica et Cosmochimica Acta. We look forward to your contributions.
