Depositional History Reconstruction of the Miocene Formations in the Carpathian Foredeep Area Based on the Integration of Seismostratigraphic and Chemostratigraphic Interpretation

Detailed recognition of the paleoenvironment of sedimentation for the monotonous series of heterolithic sediments of the Machow Formation in the central part of the Carpathian Foredeep is still relatively poor. This study presents an unconventional approach of integrating results of seismostratigraphic interpretation with conclusions from analyses of chemostratigraphic profiles in boreholes. The results obtained from the studies allowed the resolution of the seismic data to be increased, enabling it to be accurately tied to the well data. The studies showed a high consistency between results obtained by the two methods mentioned above, and their combination provided a range of additional information and conclusions that could not be drawn from using a single method. The possibility of correlating interpreted sedimentary sequences with specific elements of the paleoenvironment and stages of the depositional history of the analyzed sedimentary basin was also demonstrated. An important benefit of the integrated interpretation methodology used is the possibility to recognize an apparently monotonous profile of heterolithic formations, which was previously not possible with standard interpretation methods.
