| Abstract [eng] |
Reconstruction of the structure of the upper part of the sedimentary cover (Hercynian and Alpine structural complexes) of Western Lithuania and its visualization in 3D was the major aim of the master theses. The major tasks of this research were defined and fulfilled: -to collect the comprehensive depth data from wells and compile the relevant data base; -to compile a set of structural maps of the bottom of 37 different Hercynian and Alpine formations; -to visualize the set of compiled the structural maps in 3D. Data from more than 250 boreholes from the Western part of Lithuania were collected, the data base, containing numbers of depths of occurrence of 37 formations was compiled. Based on collected data, 37 structural maps were created and following, 3D visualization of set of compiled maps was carried out by the means of MapInfo and Vertical Mapper software. Detail structural and tectonic analysis of the compiled set of maps allowed to define the major structural units of the studied area, structural trends particular for each of studied formation, trends of the structural evolution of the studied territory, magnitude and timing of the major tectonic events and, the most important, to distinguish two absolutely new tectonic units – sub-latitudional Southern Elevation of the Telšiai Step and Telšiai near-fault Depression. |
