Quantification of the Quaternary Geological Structure Using Geological Cross-Sections in a Selected Part of the Moravian-Silesian Region for Geotechnical Purposes
MetadataShow full item record
The article deals with the quantification of the Quaternary geological structure of a selected part of the Moravian-Silesian region for geotechnical purposes (Ostrava glacigenous basin). The geological structure was quantified using the existing Quaternary cross-sections from various sources. The Quaternary cross-sections were vectorised and quantified in terms of the surface of section, horizontal length and using average thickness (average vertical length). All the data were processed for the first Quaternary layer from the ground surface. Next, data were processed for the whole Quaternary geological structure. Both the types of data are important for engineering geology, particularly for civil engineering purposes. In total, 60 cross-sections of 444 599 km in length were processed. The disadvantage of quantification is the fact that the real spatial structure is not reflected. On the contrary, the advantage is the reference quantified information on the basic types of geological environment for engineering-geological purposes for designers, engineering geologists and geotechnicians. At the same time, this resulted in the review of the existing Quaternary cross-sections. It is important to have reference quantified data on the basic geological environments in selected regions, in this case a selected part of the Moravian-Silesian Region and its Ostrava glacigenous basin.
