* **Colleagues,** *We would like to draw your attention to a topical session on advances in detrital thermochronometry and cosmogenic nuclide dating at the AGU Fall meeting this year. We welcome contributions in both method development and applications to tectonics, surface processes, and hazards. T028: Linking tectonic deformation and surface processes using detrital thermochronometry and cosmogenic nuclide denudation rates Session ID#: 9101 Session Description: Low-temperature thermochronometry is used in active tectonics studies to elucidate the dynamics of orogenesis by constrainting fault initiation and rates of motion. However, in collisional orogens, exhumation is modulated by erosion and interpretation of low-temperature (< 200°C) thermal histories requires the assumption that such exhumation is a viable proxy for fault slip rates. Thus, there is an inherent link between surface processes that shape the large-scale topography of mountain belts and thermal histories preserved within them. Cosmogenic nuclides, on the other hand, provide independent estimates of short-term erosion rates (103 -- 105 yr), via concentrations of 10Be and other cosmogenic nuclides in detrital minerals, that complement low-temperature thermal histories. This session explores advances in detrital low-temperature thermochronometry and its potential link to short-term erosion rates derived from cosmogenic nuclides. Contributions that explore new directions in detrital thermochronometry or combine thermochronometry and cosmogenic nuclide dating are especially encouraged.
