Information - IS15 - GM2.3/GD28/SSP30/TS14 Bridging timescales of landscape evolution in active orogens (co-organized by GM, GD, SSP & TS, co-sponsored by EAG)
Landscapes in active tectonic settings evolve as a result of the interactions of both exogenic and endogenic processes. The rate at which these processes operate and their relative contribution over time in sculpting the landscape is important to assess particularly in light of potential feedbacks between tectonic activity and climate. As a result it is important to quantify the rates at which processes including bedrock uplift, exhumation, erosion and deposition operate and evaluate the principle driving forces over variable timescales. Recently there has been an increase in the number of studies making use of the detrital sedimentary record, low temperature thermochronometry and cosmogenic nuclides to estimate the rates and times at which material is exhumed and removed from the surface. These studies provide insight into how the landscape has changed over timescales of millions to thousands of years. A multidisciplinary approach incorporating isotope studies and modelling is key to future advances in understanding landscape evolution.
We actively encourage contributions from those using isotopic techniques to constrain both the timing and rates at which tectonic and surface processes operate in active tectonic setting to provide insight into how landscapes evolve through time.
