Reconstruction of Rock Uplift in South‐Central Germany Since Late Mesozoic Times
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract Rock uplift and denudation act as first‐order controls on geological processes that influence atmospheric and ocean composition, and landscape‐forming processes. However, estimating rock uplift rates remains challenging due to the temporal averaging of rates calculated from individual thermo‐ or geochronologic systems.
