“…For example, in 3D seismic survey data, strike-slips extending tens of kilometers form systems of disruptions within the Mesozoic layers [15]. When interpreting data from regional 2D seismic survey profiles at deeper levels of the section, the "flower structure" is less clearly observed due to the chaotic distribution of the wave field [45]. Figure 6 schematically illustrates the manifestation of the principal and adjacent feathering dislocations of the strike-slip zone.…”

The paper presents the results of a geological interpretation using gravity, magnetic, and seismic data to understand the oil and gas potential of pre-Jurassic sedimentary intervals and basement in the central West Siberia basin. The 200 km long Pai-Khoi-Altai strike-slip zone was investigated. Reconstruction based on a data complex indicate the right-lateral kinematics of the principal strike-slip faults and possible fault inversion. The study evaluated the spatial and genetic relationship between the conditions for hydrocarbon trap development and the strike-slip fault systems, such as “flower structures”. Strike-slip geometry and kinematics are confirmed based on 2D and 3D seismic data. Geological and geophysical criteria are used to forecast localization of hydrocarbon fields. Predictive zones are elongated in several different directions and have a different distribution pattern in the blocks separated by principal strike-slip faults, confirming its significance as a controlling factor for the hydrocarbon potential of the region’s structures.

“…Correlation characteristics are widely employed in the analysis of random and deterministic signals in geosciences [13][14][15]. For instance, calculating linear and rank correlation coefficients between two fields within a moving window allows for the assessment of the strength of the relationship between the two fields and the tracking of its variation across the studied area.…”

In the study, a comparison of correlation characteristics that can be obtained when analyzing areal geophysical data in COSCAD 3D, GIS INTEGRO software, as well as in custom software with a novel approach, has been conducted. It is proposed to utilize the cross-correlation function for mapping strike-slip deformations while establishing shift parameters. A synthetic model field has been constructed, and calculations have been performed in various software packages, demonstrating the advantages of calculating the cross-correlation function within a sliding window.
