Quantifying the effect of recent relief changes on age-elevation relationships

Braun, Jean


The effect that recent relief changes may have on the distribution of rock ages with elevation is investigated for a range of thermochronometers. From the solution of the heat transport equation in a crustal block undergoing uplift and surface erosion, the temperature history of rock particles that are exhumed at the Earth's surface today is computed. These T-t paths are then used to calculate apparent isotopic ages for the (U-Th)/He system in apatite, characterized by a low (≈ 70°C) closure...[Show more]
