3D models of geological structures are a very convenient form of integration of several types of geological and non-geological data. They are a game-changer in terms of cutting down amount of time required for analysis of data – substantially enough to permit novel analyses to be carried out, including testing of natural and industrial processes scenarios, interactions between different processes as well as probability calculations in an analyzed 3D space. This is the reason why 3D geological models became a key element in technological advancement of integrated geological cartography. In this work we present a few examples that exploit those new possibilities of data integration through a geological 3D model. We look at a regional 3D model of the Lublin Basin that allows to assess overlaps between different forms of subsurface activity, we present a model of the Inowrocław salt diapir – exploring links between the geology and motion of the topographic surface, and we also discuss a model of mine infrastructure and gas and water hazards in the Kłodawa salt mine.
