Late-Orogenic Burial and Exhumation at a Major Variscan Suture Zone

Constraints from Thermal Modeling
Conference paper
Part of the Proceedings of the International Conferences on Basement Tectonics book series (ICBT, volume 5)


A two-dimensional thermal-kinematic modeling approach constrained by geothermo-barometric and geochronological data was used to investigate the Carboniferous burial and exhumation history at a major Variscan suture zone in Central Europe. Modeling suggests that during Late Viséan to Early Namurian times convergence rates between two of the main tectono-metamorphic units of the Variscan fold belt, Saxothuringian and Rhenohercynian, exceeded 30 mm/a and subsequently slowed down to 20 mm/a. Exhumation in the direct vicinity of the suture zone occurred temporarily at velocities of more than 3 mm/a. Such rapid decompression strongly suggests a significant contribution of extensional strain to the Late Variscan exhumation of the study area.
