Abstract. The article presents analysis results in the reconstruction of the tectonic conditions dynamics for the formation of local plicative deformations and rupturing under conditions of the research both the macrostructure and its local separation using the example of the southwestern area of Kalmius-Toretska kettle-hole in the Donetsk basin. Authors applied the scientific cognition method, representing a sequence of actions to establish structural links between variables and constant elements of the Investigational tectonic system, based on statistical and mathematical methods of analysis. The characteristics of the anticlinal structure formation in the studied area - fields of the "Butivska" mine were obtained. It was revealed that the initial horizontal attitude of rocks of the studied area was changed by a monoclinal attitude with a north-western dip and a north-east strike. Afterwards, under the conditions of tectonic near latitudinal compression and near meridional tension, anticlinal folding was formed. Then, under the influence of shear fields when the deformation mode was enhanced, a compression duplex was formed within which local echelon folding and fracture was formed - Oktiabrskyi fault No.1. Maps of local structures from the polynomial of the 1st order to the highest orders with a fairly large degree of generalization, as the trend surface approaches the real geological surface, show the stages of formation and development of tectonics of the region and essentially they are a phased reconstruction of the tectonic deformations dynamics. The proposed method of consistently studying the trend surfaces of polynomials of various degrees (from the 1st and above) can be successfully applied to the reconstruction of the tectonic development of various regions. Moreover, in each individual case, the size of the area being analyzed and the degree of generalization should be chosen depending on the characteristics and complexity of the tectonic structure of a particular region and the operating objectives.

Keywords: the macrostructure, the system analysis, the polynomial, local structures, compression duplexes.
