xenoliths arrived to surface from approximate depths of 35, 70 and 73 km and indicate a complex history for the mantle beneath the Sudetes. There are thermal springs in the Sudetes with measured temperatures of 29 to 44 °C. Drilling has revealed the existence of waters at 87 °C at depths of 2000 m. These modern waters are believed to be associated to the Late Cenozoic volcanism in Central Europe.

Uplift was accomplished by the creation or reactivation of numerous faults leading to a reshaping of the relief by renewed erosion. Various "hanging valleys" attest to this uplift.
