Session ID#: 18070

Session Description:
Unraveling the interplay between tectonic forcing and surface processes is a key requirement for understanding the topographic and structural evolution of orogens. Over the past several decades, significant advancements in digital tools and dating techniques including increased quality and accessibility of high-resolution digital topographic data, and innovation and refinement of geochronology, low-temperature thermochronolgy, and surface dating, has led to an explosion of high quality tectonic geomorphology research. Moreover, field and GIS-based studies are increasingly paired with sophisticated numerical models to explore landscape evolution, geodynamics, structural, and time-temperature histories from the scale of individual faults and folds, to mountain ranges, or entire orogens. In this session we solicit contributions that address this topic, particularly those integrating multiple methods and applying innovative approaches.
