*Goldschmidt 2017, 13th-18th August * We encourage abstract submissions to session* 06K: Directly Dating Faults.* *Deadline for abstract submission 1st April (https://goldschmidt.info/2017/abstracts <https://goldschmidt.info/2017/abstracts>)* We particularly encourage those people using geochronological and thermochronological tools (such as Calcite U-Pb dating, K-Ar/ Ar-Ar dating of fault gouges, use of accessory phases etc.,) to directly date tectonic processes. Keynote: Alexis Ault (Utah State University) Convenors: Catherine Mottram <https://goldschmidt.info/2017//userView?userId=pngurevarLLzbggenzKKcbegLLnpLLhx> , Perach Nuriel <https://goldschmidt.info/2017//userView?userId=ahevryKKtfvLLtbiLLvy> "Recent advances in geochronological and thermochronological methods and applications permit the direct-dating of the formation and evolution of brittle and ductile deformation structures from a variety of tectonic settings. The combined use of geochronology (i.e., U-(Th)-Pb), thermochronology (i.e., K-Ar, Ar-Ar, (U-Th)/He), stable isotope geochemistry (i.e., H, O, and C), with both micro (i.e. crystallographic deformation textures), and macro textural and structural observations, has allowed quantification of the timing, tempo, and nature of deformation. Here we invite contributions from researchers using any of the above techniques to directly-date faults and decipher the thermal, temporal, fluid-source, fluid-rock interactions, and deformational history of fault systems at different crustal levels. The session will focus on recent advances in understanding of the full spectrum of fault behaviour, from the earthquake cycle, to shear zones, via multi-faceted approaches, involving, for example, radiogenic, stable and clumped isotopes to date and characterise the evolution of fault zones, both in the brittle and ductile regime." https://goldschmidt.info/2017/program/programViewThemes Many thanks, Catherine -- *Dr. Catherine Mottram* Lecturer in Structural Geology and Tectonics School of Earth and Environmental Sciences, Burnaby Building University of Portsmouth Portsmouth PO1 3QL 02392842300 http://catherinemottram.weebly.com/
