### Integration of Chemostragraphic and Seismostragraphic Research  
The next work stage involved following the variability of the features of the geochemical record in the wells and verified that the determined chemostragraphic intervals are reflected in the results of the seismostragraphic interpretation. The correctness of the tie between the interpretation results obtained using the seismostragraphic and chemostragraphic methods was verified by comparing the directions of seismic dips obtained on the chronostragraphic image with the record of the six-arm dipmeter (SED), as well as with information from the high-resolution borehole micro-imager (XRMI). The dips and azimuths of the layers measured with a six-arm dipmeter most often correlate very well with the systems of chronostragraphic horizons. Variations in dip values also correspond with the boundaries of depositional systems tracts and depositional sequences. The fault planes interpreted independently on the chronostragraphic image can be traced on the six-arm dipmeter. Moreover, the interpreted sequence units were related to gamma-ray log shapes. The tying of well information to the analysis of seismic sequences was carried out with reference to the current state of recognition of depositional environments and the processes that occur in such environments [21; 53]. The research performed showed a high correspondence between the results obtained by the aforementioned methods, and their integration allowed further conclusions to be drawn that were not possible on the basis of a single method. An example includes the conclusions that indicate the existence of possible anoxic paleoenvironmental conditions during the sedimentation of the lowermost part of the Machow Formation. Meanwhile, the seismostragraphic analysis shows that the paleoenvironment of sedimentation for this part of the profile can be described as a stagnating shallow basin located on a tectonically elevated basement block. Moreover, the results of both methods show unambiguously that a phase of major tectonic remodeling occurred after the deposition of these formations in the basin. These conclusions would have been impossible to obtain from a standard analysis of well logs, as well as from a standard interpretation of seismic imaging. A significant benefit of the interpretation methodology used is the possibility of recognizing an apparently monotonous profile of heterolithic formations, which has not previously been possible with standard interpretation methods, mainly due to the lack of heterogeneity of the recording well logs within the series. The series currently established based on the chemostragraphic studies provides a basis for distinguishing individual parts of the profile, differing in their geochemical characteristics. Furthermore, the series thus defined correlates very well with the sequence units interpreted from the seismic data in the chronostragraphic image (Figures 8 and 9). This may be crucial in correlating the autochthonous Miocene formations because apparently similar profile fragments (with similar lithology) in the geophysical record may have different origins, related to distinct alternation areas and different deposition directions and processes, and may have been deposited at different times.
