Modeling of the volcanic structures neotectonic evolution of Vyhorlat-Hutyn ridge (The Ukrainian Carpathians)

The geomorphological and tectonic evolution, spatial and temporal distribution of neotectonic movement amplitudes during after volcanic stages, the determination of tectonic activity are still the main problems of Carpathian geology. In the paper the results of the structure-morphometric analysis of Kuchavskyi, Syniak, Dekhmaniv volcanos have been shown. The structure-morphometric models, analytic operations with geodatabase design and spatial modeling have executed in GIS. The detailed analysis of relief evolution and tectonic movements has carried out. The uniform distribution of uplift amplitudes for Kuchavskyi volcano, high differentiated – for Syniak and differentiated – for Dekhmaniv volcano have been determined. The differences of tectonic evolution between Grabowsk volcano-domical structure and caldera of volcano Syniak, between interior and middle zones of volcano Dekhmaniv have been determined. Tectonically active local structures have been found. The amplitudes of the tectonic movements, generated as a result of Grabivska structure and Dekhmaniv volcano intrusive bodies uplift have been defined. The process of volcanic centers destruction has been determined.
