Zusammenfassung
This work constitutes the preliminary results from the first phase of INTEGRATE, a project lying within the scope of the SPP: Mountain Building in 4-Dimensions (MB 4-D). Although the crustal and sub-crustal structures of the Alps are some of the best studied of any orogen in the world, different hypotheses still exist regarding plate architecture and the nature of the subduction system. Rheological configurations of the different crustal units and lithospheric mantle, isostasy in the orogen-foreland system, and variations of flexural rigidity along and across the mountain belt, at the present-day, poorly constrained with relation to spatial patterns of seismicity. The primary goal of INTEGRATE is to provide insights into these questions by generating a gravity constrained, 3D structural model of the Alps and their foreland basins, so that a lithospheric temperature field can be calculated and ultimately the distribution of deformation and seismicity derived across the whole region. Here we present a first 3D structural model of the entire Alpine orogen, constructed from an integration of all publicly available geoscientific observations on the study area. Our model will be constrained by gravity fields, and the results of previous models generated using similar techniques, in regions that overlap our study area, such as the Rhine Graben, the Molasse Basin and the Po Basin. Additionally, it will benefit from current efforts by the AlpArray Gravity research group to create high resolution terrestrial gravity fields of the region. A combined model such as this will provide estimates of flexural rigidity, loads, gravitational potential energy and stresses in the different crustal bodies and, additionally, allow testing of existing isostastic models of the lithosphere. These 3D models have the potential to be used as a reference for other types of data processing and are a crucial step forward in deciphering how deep-seated mass changes affect the evolution of an orogen.
