If you're thinking about EGU next year, 22 – 27 April 2012, then we would like to draw your attention to the Thermochronometry session (IG10), details are appended below, and invite you to consider submitting a paper to the session. A good 'warm up' to Thermo2012 in China later in the year perhaps? Abstracts are submitted online (please follow the link below) and applications for financial support are also submitted online (please follow link below). Hope to see you in Vienna in April 2012.

Geochronology, the science of dating rocks and determining the time sequence of events in the history of the Earth, underpins modern, quantitative geoscience. Thermochronometry extends this science by determining the temperature a rock sample experienced at a particular time, or times, in the past, i.e. the rock's thermal history and enables us to study and quantify a whole range of processes that are important to understanding how the Earth evolved.
Examples include quantifying the tempo of formation and destruction of the Earth's surface topography that is strongly regulated by erosional processes, the mass and chemical exchange between continents and oceans and the consequent recycling of crustal materials into the mantle and in geological processes controlling the long-term CO2 levels within the atmosphere. Quantifying the timing, amount, rates and spatial patterns of major thermal and/or erosional events is therefore crucial to developing a full, quantitative understanding of how the Earth works. Such information is routinely obtained from thermochonometry, principally 40Ar-39Ar, apatite (U-Th)/He (AHe) and fission-track (AFT) . The fidelity and scope of these methods continues to grow through improved modelling techniques and combination with geochronometers such as U-Pb and Sm-Nd.
This session invites studies that review and discuss the current state-of-the-art of thermochronometry techniques, present new and innovative applications and discuss advances in theory and approaches to deriving thermal histories and quantification of erosion.
