Beschreibungen/Notizen

• Looking back on more than five years of DEKORP'S activity the great increase of our knowledge on the deep structure and evolution of the Variscan mountain belts in Central Europe is reviewed. Collisions and sutures have been imaged, and especially in the Rhenohercynian a complex interwedging and interfingering of crustal units are observed. Similar processes can still be verified in the Moldanubian/Saxothuringian area of the Oberpfalz on the flanks of the large Bohemian Massif. In contrast, the center part of the Moldanubian and Saxothuringian shows numerous signs of post‐Variscan crustal modifications, like flattening and equilibration of the Moho, lower crust lamination, thin mafic lower crusts and many plutons, possibly responsible for the rather transparent upper crust. These and other types of reflectivity and their correlation to tectonic terranes and their boundaries can be explained by different thermal histories and different heat supplies with their strong impact on crustal rheology.
