Summary. The attractiveness of the shelf
sedimentary basins of the Caspian Sea region, and, firstly, the most accessible
of them - the active margin of the Scythian-Turanian platform, is associated
with the improvement and detailing of the existing models of the geological
structure and history of development of the region. The purpose of the
presented work was to create geological models of the structure and restore the
evolution of sedimentary basins of the transitional part of the Middle Caspian
and South Caspian basins based on the accumulated data of drilling and seismic
exploration in the water areas and geological survey in the adjacent land
areas. The article reflects the information content of seismic sections across
different parts of the region, which exhibit varying seismogeological
conditions. The clarification of wave-formed objects, determined by objective
seismic parameters such as the configuration and relative positioning of
reflections, their continuity, as well as the amplitude and frequency of
seismic waves, served as the foundation for conducting seismic stratigraphic
analysis of the wave field. Based on an analysis of these conditions, the
authors have clarified and defined four distinct seismic horizons: SH-A, SH-I,
SH-II, and SH-III different parts of the region, each characterized by unique
seismogeological conditions. These seismic horizons were delineated according
to reflection dynamic expressiveness, length, and the resolution. The article
highlights that the tracking quality of these horizons varies significantly.
Schematic structural maps compiled from these analyses illustrate the
geological structure of the Red-colored strata and Akchagyl sediments, and
effectively correlate their structural plans.
