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 #1.

Highlights

The most important task of modern tectonics from the point of view of applied geological research is to study the dynamics of the deformation process in the rock strata, which lead to the formation of tectonic structures
The nature of the deformations of any genesis and the conditions for their occurrence are investigated by structural analysis methods – one of the major methods of tectonic research, which is based on the studying the morphology of structures
It is quite obvious that a local area of methane accumulation can be identified only based on knowledge of the causes and mechanism of tectogenesis of the tectonic unit being analyzed, ideas about the genesis and the nature of mining processes occurring in the massif and using modern methods of computer analysis of field data on the base of their mathematical processing

Summary

Introduction

The most important task of modern tectonics from the point of view of applied geological research (gas generation, oil generation, ore formation, etc.) is to study the dynamics of the deformation process in the rock strata, which lead to the formation of tectonic structures. The nature of the deformations of any genesis and the conditions for their occurrence are investigated by structural analysis methods – one of the major methods of tectonic research, which is based on the studying the morphology of structures. It is quite obvious that a local area of methane accumulation can be identified only based on knowledge of the causes and mechanism of tectogenesis of the tectonic unit being analyzed, ideas about the genesis and the nature of mining processes occurring in the massif and using modern methods of computer analysis of field data on the base of their mathematical processing
