The relevance of the work is due to the scientific substantiation of the geological structure of the section of lower Carboniferous deposits in the territory of the Astrakhan arch using the latest data of geological and geophysical materials. The purpose of the study is to analyze data from drilling parametric and exploratory wells to dissect the section of this territory and determine the cyclical nature of sedimentation and zonal distribution of lower Carboniferous rocks. The study methodology was based on data processing of field Geophysics materials - seismic exploration and well drilling, as well as laboratory data on the study of core and sludge materials. The author summarized the extensive geological material obtained in the course of geological exploration on the Astrakhan arch, which allowed to restore the course of precipitation accumulation. For rocks of the lower Carboniferous age of the southwestern part of the Caspian basin, the characteristic of sedimentation and lithological composition is given, and the analysis of all the actual material about the growth and distribution of rock types is carried out.

Key words: Caspian depression, Astrakhan arch, low-carbon deposits, type of section, well
