In my project, I am developing an inverse model to quantify the spatial and temporal exhumation history of the Chilean Andes, using own and literature low-T thermochronological data as model inputs. The constrained exhumation rates are compared to the structural and climatic evolution of the orogen to get insights into the response of erosion to climatic variability and tectonic changes. As a second project, I am investigating the influence of glacial erosion on exhumation at the latitude of Santiago, where the geology is well constrained and remained relatively stable since the last 23 Ma. I use a thermo-kinematic model, modified from Riesner (2017, PhD thesis), to simulate thermochronological ages using geologically constrained fault kinematics and observed shortening rates. </br>Modelling of thermochronometric data requires a good understanding of the surface evolution, since relief formation modifies the subsurface thermal field. Attending to your workshop would enable me to improve my competences in landscape evolution modelling. In turn, I could contribute to the understanding of (inverse) numerical models to constrain exhumation using low-T thermochronological data.tion using low-T thermochronological data. +
