Abstract
The article describes the features of display of faults on the territory of Kryvyi Rig mining area, characteristic of which is different by complicated tectonic structure and covers the main stages of the formation of the crust from the lower Archaean till Late Proterozoic. Faults in the form of wide zones of concentration of gaps, fractures, mylonitization, cataclase, brecciation, magmatism, metamorphism, play a major role in formation of the modern fold-block structure of Kryvbas are well traced in geophysical fields. The main fault structure of the district is the trans-regional deep Krivoy Rog-Kremenchug fault that within Krivbass is presented by multi- axial system of faults: western axis — West fault; the central axis — Tarapakovsky fault; Eastern axis — Saksagansky and East faults. Almost all regional faults consist of two or three closely spaced parallel ruptures. By length, the inner overlay, behavior in geophysical fields in Krivbass the faults are subdivided into three groups: submeridional, corresponding to general spread of the main folded structures; diagonal, corresponding to the spread of the basic fold structures; sub-latitudinal that are transverse to the spread of folded structures.

The study of convergence of additive-averaged splitting based on the scheme of explicit solution for three-dimensional equations of convective diffusion
Modern mathematical forecast models are based on hydrodynamic equations, which are three-dimensional convection diffusion equations in the general form. In the article, the new approach to solving such equations, which c...
Formation geological depth image according to refraction and reflection marine seismic data
The possibility of forming of the geological depth image from marine seismic data observed with the method of reflected waves by multiple overlaps and the refracted method by deep seismic sounding was investigated. The d...
