Essay

The analysis of features physical and geological feature of rock sphere of the Priazov geoblock Ukrainian shield is dictated by presence here tectonic magmatic of patterns containing field of many mineral resources. Results of all-up studies of such patterns were constructing a consecutive line 1D-2D-3D of geophysical models. Source the one-dimensional model, which one was: optimum corresponded to the averaged source geophysical fields; had internal conformity between physical arguments of geologic environment; formed the basis for constructing more highly information of two and three-dimensional models. The subsequent model - two dimensional, has allowed to receive the complementary information on physical heterogeneities and features of a geological feature of various structural members of earth crust of the Priazov geoblock and served that foundation, concerning which one was constructed regional and mean scale close set 3D gravity of model. The complex of geophysical methods with the subsequent constructing close set 3D gravity of models on a gravitational field has allowed to execute volumetric mapping of earth crust of the Priazov geoblock. The results of the executed studies demonstrate, that the top of a crust of the Priazov geoblock is folded sedimentary volcanic by formations resized by a metamorphism, metasomatosm and breached by intrusive bodies. In the upper and mean crust of the Berdyansk block is established large Obitochnensky granite diorite batholit, having a difficult constitution on different depths in earth crust and in the upper mantle. Is allocated and is in detail characterized on a complex of geological-geophysical methods plutonic Pavlovsko-Volodarsky fault, which one separates Western Priazov granite-gneisis block from East Priazov subalcalinous block. The material filling up and difficult plutonic constitution of Telman volcanic ring structure having mantle location is rotined. By results of large-scale volumetric simulation the morphology and features of material structure ofVolodarsky and Kremenevsky subalcalinous massifs is learnt.
