The purpose of the work is to determine the state of study and the prospects for further research on the vertebrate animals remains from the Mesozoic deposits of the Lugansk region. To achieve this goal, collection and generalization of information on the locations of vertebral remains among the Mesozoic deposits of Lugansk region were made. Despite the considerable amount of findings of various groups of Mesozoic vertebrates remains in the Donets Basin territories adjoining them, their systematic and purposeful study, unfortunately, was not conducted in Lugansk region, although indications of the findings of the Mesozoic vertebrates remains in the Luhansk region occur quite often.As a result of the processing of published materials and preliminary interpretation of field observations, a list of 20 sites located mainly on the right bank of the Siversky Donets within the Lugansk region is compiled. Almost all the places are confined to the Upper Cretaceous deposits, much less – to the basal layers of the Paleogene and only one to the Triassic. The vast majority of the locations of the Upper Cretaceous are confined to the area in contact with an array of coal deposits (the so-called "open Carboniferous"). Outwards from it, the rocks are more open-sea and they drastically reduce the diversity of the fossil fauna. Therefore, outlining the range of promising areas regarding finding vertebrate animals remains one should be aware of the above-mentioned pattern of their placement. Triassic deposits of the Donbas are not at all investigated for finding the remains of vertebrates, although their potential is very significant. Nevertheless, due to the small area of the Triassic deposits outcrop in the Lugansk region, searches need to be directed to the west – in the Donetsk and Kharkiv regions.The problem of solving the ecological and geological issues which arise as the result of working off in natural resources (in particular the deposits of potassium salts) is actual at this time. Specificity is in easy solubility of salts and therefore the creation of artificial cavities and karstic phenomena. The article examines the ways to solve the problems of mapping the salt karst and forecasting creation of dips and subsidence of the earth's surface by the example of Kalush-Holyn potassium salt deposit which is located in Ukrainian Precarpathians. As the basis of the research, the complex geophysical methods were considered. It was proved that the method of natural pulsed electromagnetic field of the Earth (NPEMFE) can be selected as a reliable evaluation method of stress-strain state of rocks and prediction of karst processes and deformations which is associated with the presence of extracting chambers. The article describes the physical preconditions for applying the method, sets out the basic postulates of field intensity anomalies classification and proposes the methodology for depth evaluation. Using the real examples - the profile and planar research of potassium salt deposit - the succes of the NPEMFE method is shown, along with its effectiveness to solve some ecological and geological problems, as well as feasibility of using the method in other areas.
