Permo-Mesozoic Mid-Polish Trough formed eastern segment of the Southern Permian Basin, within which thick series of the Upper Permian (Zechstein) evaporites, including rock salt, have been deposited. During subsidence phase the presence of thick salt series led to regional decoupling between sub-salt basement and supra salt Mesozoic sedimentary cover, and to development of various salt structures. Evolution of salt pillows and diapirs was genetically related to activity of the basement fault zones. The Goleniów, Dzwonowo-Człopa, Damasławek, Mogilno, Kłodawa and Lubień salt diapirs have been analyzed using conventional seismic reflection data acquired during petroleum exploration, and - in case of Damasławek and Lubień diapirs - shallow high-resolution seismic data. Interpretation of available seismic data gave new insight into geometry of these salt structures, finally shaped during Late Cretaceous-Palaeogene inversion of the Mid-Polish Trough and partly modified during younger (Neogene- Quaternary) phases of their tectonic activity.
