Exponential development of informational technologies allows providing data on interior structures of the Earth independently of geophysical methods of exploration. In the present work, a three-dimensional model of tectonic break of a block of crust based on decipherment of aerial and satellite images of different degrees of detail was developed. The decipherment was conducted by the method of scale approach from regional level to local. The methodological approach applied by us was developed in works of Yu.V. Nechayev and based on allocation of lineaments, calculating their specific length and evaluation by obtained parameter of the tectonic break degree at a given depth. For initial data we used the results of experimental and methodological works, namely maps of tectonic cracks and schemes of ring and volcano-tectonic structures. The content part of the model was implemented using ArcGIS software package, and three-dimensional visualization was made by Oasis montaj viewer. The model validity in comparison with well-known geological structures is assessed. The correspondence of the model to reality is confirmed by reflection in it of well-known geological structures. The developed model demonstrates the position of destruction zones in the most top part of the Earth’s crust, and gives the possibility to specify and predict geological structures and associated mineral deposits. The model is useful in integrated interpretation of materials of geophysical and geochemical researches and for tectonic reconstructions.
Keywords: decipherment, specific length of lineaments, lineament analysis, Earth crust structure, low/high fractured area, aero- space image, cell square, ArcGIS, Oasis Montaj
