Evaporites (sulphates and halites) of Zechstein PZ1, PZ2 and PZ3 cyclothemes occur in the NW part of Mazovia-Lublin Graben (SE Poland), for which the 3D model of geological structure was created in 2012-2016. Available geological data from boreholes (well logs and descriptions of cores and crushed rock samples) enabled to precise the occurrence parameters (depth and thickness) and the supposed extent of studied evaporites as well as to define 8 facies types, represented various depositional settings. Several maps, illustrating facies distribution of each evaporitic lithostratigraphic unit, supported with 3D images of main lithological-facies components of mentioned cyclothemes allowed to comment the environmental changes in the Mazovia-Lublin Graben area during evaporitic periods of studied cyclotheme successions.
