Short summary
Short summary
Legacy 2-D seismic data with newly acquired 3-D seismic data were used to construct a new model of geological evolution of NW Poland over last 400 Myr. It illustrates how the destruction of the Caledonian orogen in the Late Devonian–early Carboniferous led to half-graben formation, how they were inverted in the late Carboniferous, how the study area evolved during the formation of the Permo-Mesozoic Polish Basin and how supra-evaporitic structures were inverted in the Late Cretaceous–Paleogene.

Short summary
Short summary
A new analogue modelling approach was used to simulate the influence of tectonic extension and tilting of the basin floor on salt tectonics in rift basins. Our results show that downward salt flow and gravity gliding takes place if the flanks of the rift basin are tilted. Thus, extension occurs at the basin margins, which is compensated for by reduced extension and later by shortening in the graben centre. These outcomes improve the reconstruction of salt-related structures in rift basins.

Short summary
Igneous intrusions that could be associated with volcanic eruptions on Earth’s surface can be also seen on geophysical data at great depths, well beyond the reach of boreholes. Our results show how advance analysis of seismic data together with regional geological information could be used to predict their key characteristics such as lithology, thickness and overall geometry that are necessary in order to understand Earth’s magmatic activity.
