Summary of thesis

This project intends to study the well-preserved source-to-sink Pyrenean Foreland basin to quantify the chemical weathering evolution in the entire sediment routing system. This will be done by combining Hf and Nd isotope analyses with clay mineralogical analyses on samples from the entire Foreland basin. The types and abundances of clay minerals will serve as a record for variations in the erosion rate and chemical weathering both by tectonically and climatically induced surface processes. Additionally, Hf and Nd isotopes, which have found to have different geochemical behaviors in Earth's surface conditions, will be used as markers for understanding chemical weathering rates and intensities. Clay and isotopic analyses will be coupled with different proxies to estimate climate variation that will serve as validation methods.
