3D Modelling of Crustal Structures in the eastern Alps Under Constraining Conditions. It enables us to combine many available constraining data sets directly with the 3D model. The actual density model was optimised for the Bouguer anomaly and topographically reduced geoidal undulations. The model shows a division into Northern Pre-Alps, central Eastern Alps and Southern Alps. While the northern and southern crustal parts belong to the European and Adriatic crusts, respectively, the central Eastern Alpine area is characterized by a melange of the Adriatic and European crusts.
Second order influences to the two fields are of different origin.
In the case of the topographically reduced geoidal undulations the subcrustal density domains are the main additional source. This modelling of the lithospheric features allows us to calculate the distribution of loads in the study area. Knowledge of the load distribution is the first step in calculating the effective elastic thickness of the lithosphere in the Eastern Alps. 3D Inversion von Schwerefeldern mit Hilfe der Euler-Dekonvolution.
