Abstract

The results of high-precision integrated geophysical studies of the Ivano-Frankivsk National University
territory are presented. Research methods used are electrical prospecting and gravity and magnetic prospecting. According to the results of geodetic measurements and field geophysical observations, heights maps of the territory, regional components and detailed maps of local anomalies of the gravitational and magnetic fields, and also, according to the data of vertical electrical sounding, geoelectric sections along interpretation profiles were constructed. For the construction data on the geological and tectonic structure of the section to the depths of the first hundred meters were used, as well as geophysical materials obtained in previous years through of the Ivano-Frankivsk city territory. The analysis of the general behavior of the regional components of the gravimagnetic fields and morphology of geophysical anomalies was performed. The geological interpretation of the identified individual local gravitational and magnetic anomalies is presented. A regional field of gravity tends to increase in the direction of increasing heights in the study area and the regional magnetic field has an insignificant, but inverse relationship. A series of positive small intensity local anomalies of the field of gravity is probably due to the rocks of the Kosovska and Tyraska suite, for example, compacted carbonates or anhydrites. Local magnetic anomalies have a relatively small intensity ranging from -100 nTl to 50
0 nTl and due mainly to university facilities and communications. According to the results of the analysis of the intensity of geophysical fields, a general forecast estimate of the ecological state of the research area is presented. The obtained field intensity values are much lower than the sanitary norms.
