Based on the spore-pollen data, the mineral composition of clay rocks, analyzed structures and facies, and a general paleogeographic analysis, the sedimentation conditions and landscapes of islands located during the Late Bajocian in the region of the present-day the Crimean Mountains have been reconstructed. It is shown that the sublatitudinally elongated insular land zone had a width of 30 km, the heights of the islands were no more than 1 km, with steep mudflow-affected northern slopes and with an extensive river system on the southern slopes.

A brief account of the evolution of Russian airborne geomagnetics is given. It is shown that the development of aeromagnetic systems based on unmanned aerial vehicles (UAVs) is of great interest. This paper presents theoretical and experimental data that concern the development of the optimal UAV layout in order to create a UAV-based aeromagnetic survey system using a new-generation optically pumped quantum rubidium aeromagnetometer. The new UAV-based aeromagnetic system is planned for use for high-precision aeromagnetic surveying at low altitude (30 m and more) for geological, engineering, and environmental applications.

This article provides the results from studying the upper part of the section of the entire Caspian artesian basin. The stratification map, the profile section and the isohyps map of the roof of the upper hydrogeodynamic zone were compiled on the basis of generalization of geological and general hydrogeological data. Systematized hydrogeological data on the depositional conditions, structural features and nature of the distribution within the upper hydrogeodynamic zone of the Caspian artesian basin, as well as the supply zones and the areas of transit and discharge of underground waters are provided. The borders of the upper hydrogeodynamic zone of the basin have been drawn as a result.
