The purpose of this study is to identify the peculiarities of the formation and location in the structure of urban spaces, modern wooden temple architecture, its harmonious coexistence with the existing residential and public environment of Lviv. There is also a need to show the features of the material (wood) and its relief, namely the texture as a component of the perception of image and form, which accentuate the building of the temple in the urban spatial structure of Lviv.

Objective. To identify the location of potentially active seismic zones in which local earthquakes may occur. To evaluate the predicted seismic shaking intensity (in MSK-64 scale points) considering impacts associated with the local tectonic and engineering-geological conditions of the study site. Methodology.

Integrated analysis based on spatial and temporal correlation of sedimentation, tectonic movements, magmatism and metamorphism made it possible to establish the main geodynamic peculiarities of geological history of the Carpathians during the Alpine tectonic epoch. Two historical turning points - the beginning of Cretaceous and the beginning of Miocene - are the most significant for the whole area of the Carpathian Arc.

Peculiarities of anomalous magnetic field in Ukrainian Carpathians territory were considered. It was stated that on the base of magnetic anomalies characters in can be divided in 4 zones that generally matches with main tectonic elements of the region (in SW – NE direction): Transcarpathian trough, Folded Carpathians, Precarpathian trough, SE edge of East-European platform. It was concluded that the peculiarities of geological structure and tectonics of Carpathians are reflected in anomalous magnetic field of the region.

The tectonic units of the Carpathians are considered in terms of the terrane analysis. The Flysch Carpathian nappes and Samdir molasse unit are regarded as the ancient accretionary prism. Growing the prism was caused by the Alpine subduction of the Carpathian Flysch basin basement beneath both the ALCAPA and Tisza-Dacia terranes. At the Cretaceous-Paleogene time the Fore-Marmarosh flysch prism was formed in the front of TiszaDacia terrane and the Pieniny Klippen Belt – Monastyrets–Magura – Duclya wedge was builded in the forland of ALCAPA one.

The tectonic units of the Carpathians are considered in terms of the terrain analysis. Carpathathian orogen is build up of three main elements: microcontinental terrains, sutures and flysch-molasse accretionary prism. There are two main terrains: a northern ALCAPA and a southern Tisza-Dacia. Sutures (Fore-Marmarosh suture, Pieniny Klippen Belt and others), marking the ancient oceanic basins, bound these terrains. The Flysch Carpathians are regarded as the Cretaceous-Neogene accretionary prism.

Purpose. The aim of the research is to study the geological structure of the Peninic nappe of the Ukrainian Carpathians taking into account new data of geology and geophysics. Methodology. The research methodology includes a detailed comprehensive analysis of geological survey data, prospecting, drilling, and geophysical studies of the Peninic nappe. Results. The Peninic nappe include the rocks of Triassic – Oligocene ages is the South-West unit of the Outer (Flysch) Carpathians.

Purpose. The aim is to identify the structural forms of the lateral extrusion in the Western Ukrainian Carpathians and to create the preliminary conceptual model of its forming. Methodology. Methods of the geological mapping and structural analysis were used. The analysis of the fault-related folds and others deformations including melange, restoration of the stress fields by the standard method using the conjugate shear fractures and decryption of the satellite imagery played an important role especially in the diagnosis of the strike-slip zones.

Perspectives of the creating of the new physical models concerning the structure of the Earth, their evolution and methodology of the structure classification and parameter measuring of the Earth’s physical fields are analyzed. It is pointed out that investigation of the deep structure, composition and geodynamics of the continental and oceanic lithosphere gives the possibility to distinguish the system connected with global processes of Earth’s development (rifts, uncompensated deeps, continents, oceans). 

Purpose. The purpose of researches – to analyze the characteristics of modern geodynamics, tectonics and seismicity of Carpathian region of Ukraine and its components – the Folded Carpathians, Transcarpathians and Precarpathians. Methodology. The methodology includes a detailed complex analysis of the deep structure and seismotectonic activity in the region and its separate zones on the basis of specially developed methods of refinement the coordinates and depth of local earthquakes sources and complex of geological and geophysical data. Results.
