Depth structure of the Gorishne-Plavninsk structure and general principles of geological and geophysical study of the Krivoy Rog-Kremenchug iron-ore strip

The article presents the results of newest research performed by State Enterprise «Ukrainian Geological Company» and Institute Geophysics National Academy Sciences Ukraine in 2021 to find out morphology elements occurrence an redeposit within limits Gorishne-Plavninsk-Lavrikovsk area Krivoy Rog-Kremenchug iron-ore strip. In process geological geophysical studies, a large body new data was obtained regarding deep structural morphological features construction Gorishne-Plavninsk structure (GPS), associated with Krivoy-Rog fracture zone.
 Materials reinterpretation previously per formed ground-based magnetometric gravimetric surveys, detailed high-altitude aeromagnetic studies study density magnetic properties rocks, including anisotropy susceptibility using equipment techniques, gravimagnetic modeling three-dimensional volume model lead conclusion that this is typical drag fold pronounced reversal its southern part right-hands hear. Its primary formation occurred as faulted band sedimentary-volcanogenic extrusive formations subvertical bedding spreading depth at least 1.5—2 km.
 A complete kinematic analogue GPS studied Likhmanovsk structure, located most Many structures Middle Bug are close it kinematics, faulting doubtful sedimentary genesis were mentioned earlier. All these require approach some other deposits Ukrainian Shield fault tectonics, well problems stratigraphy rocks Early Precambrian.
