Аннотация: This paper is dedicated to research on structural position of magmatic formations in the area of educational and research site of Geological Faculty, LomonosovMoscow State University, located in the Bakhchisaraidistrict in Crimea.In this area, magmatic formations are represented in all their diversity. There is no consensus about the form of intrusions occurrences.In different years, the same arrays of igneous rocks were considered as diapirs, stocks, laccoliths, and plate bodies.Petrophysical measurements on“Bodrak formation”outcrops near theTrudolubovka village, showed that intrusive bodies have a high contrast in magnetic susceptibility.It creates prerequisites for mapping dikes and intrusions hidden under a thin layer ofsame age volcanogenic-sedimentary rocks. To understand the depths and geometry of intrusive bodies near mount Kremennaya, the authors performed a two-dimensional magnetic modeling of magmatic bodiesstructural positions. It showed high variability of models using only induced magnetization. The authors demonstrated that using of paleomagnetic data and determination of thermo-residual magnetization vectordirection will make it possible to determinemore reliably the structural position of magmatic bodies, which is important for explanation of magmatismin the region.
