[S-GL35] [EJ] Constructing 4D Timing, Thermal and Fluid Flow histories of fault and deformation zones.
Thu. May 25, 2017 10:45 AM - 12:15 PM Poster Hall (International Exhibition Hall HALL7)
This session will highlight new research directions in geochronology, thermochronology and fluid flow that contribute to the understanding of the 4 D evolution of fault and deformation zones. Continuing advances in the understanding and integration of isotope geochemical and geophysical methods enables geoscientists to decipher and constrain the timing of deformation zone processes including geochemical fingerprinting of involved fluid sources, potential fault reactivation and thermal history through geological time.
An enhanced understanding of the origin of involved fluids ranging from meteoric to deep formational fluid sources, their pathways in the shallow crust and different geotectonic settings are of paramount importance to decipher deformation processes in the crust. Interpretation of fault zones and their unique isotopic geo-/thermochronometric records have applications in many areas of fundamental and applied science, including structural geology, landscape evolution, natural resource appraisals and paleoclimate-tectonic linkages, dating of active neotectonic faults will assist with seismic risk management and studies of earthquake recurrence intervals using OSL, TL, ESR and other techniques for dating geological young active faults. Here we invite contributions that further our understanding of fault development - deep to shallow - with a particular focus on interdisciplinary studies aiming at linking fault chronologies, deformation conditions and fluid circulation,
