N1 - The authors are grateful to the reviewers T.M. Parfenova and Yu.F. Filippov for detailed analysis, fruitful criticism and valuable comments, which helped to significantly improve the text. This study was performed as part of the basic research project No. FWZZ-2022-0008 “Digital geological and geo-physical models of the Lena–Tunguska and Lena–Vilyui petroleum provinces, analysis of the distribution trends of oil and gas fields, assessment of hydrocarbon potential of the main Upper Proterozoic and Phanerozoic plays, including Vendian and Cambrian carbonate horizons with hard-to-recover resources, the study of the influence of trap intrusions on hydrocarbon potential.”.

N2 - The results of regional geological exploration over the past 18 years within the Aldan–Maya potential petroleum area were used as the basis for the refinement of the geological structure of the study area. The study considers the key structural features of the sedimentary cover of the Aldan–Maya region and major tectonic events that affected its structure. The generalization and interpretation of regional seismic survey data provided the basis for building a series of geoseismic sections and structure maps, which, in turn, were used in structural tectonic zoning of the study area. The map showing outcrops of Riphean formations and groups on the pre-Vendian erosion surface was complied. Tectonic schemes for three structural levels (upper Karelian–Lower Riphean, Middle–Upper Riphean and Vendian– Cambrian) confirmed their fundamental difference. In particular, the large Maya inclined swell was detected only in the topography of the Lower Riphean and is absent in the overlying structures of Middle Riphean–Vendian age, which are represented by weakly differentiated monoclines. The parameters of the major tectonic elements were determined.
