A 3D geological modelling methodology is briefly presented in this work. This procedure allows to reconstruct complex geological bodies using topographic and structural-geological data. The main constraints considered for the geological surfaces reconstruction are the geological cross-sections. GIS (Geographic Information System) tools and functions have been exploited for 2D data management, while gOcad® software for 3D modelling. The proposed methodology consists in three main steps: i) data acquisition; ii) data storage in a GIS; iii) 3D surface and volume reconstruction. This methodology has been applied for the 3D reconstruction of the Monte Misma anticline (Bergamo), localized in the thrust and fold systems of the frontal part of the Central Southern Alps. This 3D geological reconstruction allows to check and improve the geological interpretation of the buried surfaces. Moreover the geological surfaces and volumes definitions can be very useful in the different environment of the Earth Sciences (eg. oil exploration; numerical modelling; geophysical data processing, etc.).
