Abstract

This work aims to show how geological maps can be used for the 3D modelling of complex geological bodies. Geological data must be organised in a Geographic Information System and then imported in GOCAD, a software which allows the creation of 3D surfaces, solids and grids using points and linear elements. A deep-seated slope gravitational deformation developed in the Triassic sedimentary cover of the Southern Alps (Val Taleggio, BG) has been reconstructed. This phenomenon occurs in a complex structural setting comprising thrust faults crossed by strike-slip and normal faults. 3D modelling is mainly based on topographic, geological, structural, and morphological linear features. In this way a direct control of bi-dimensional interpretations is possible, leading to a better understanding of complex geological bodies, and as a base for geomechanical modelling.
