The paper deals with the geology and mining history of the quarry Kernberg in Krušné hory (Erzgebirge, Ore Mountains) between Jindřichovice and Rotava. The locality was the largest basaltic quarry in the former Czechoslovakia. The historical review is followed by the geological description, mainly volcanogenic rock (nepheline-basanite and pyroclastic) incl. petrography, mineralogy, chemical composition, tectonic, structural and pedological conditions. Finally, the origin of the locality is discussed. There were explosive and effusive periods recognized at Kernberg.
Are there preserved volcanogenic inter-bed layers (known as tonsteiny) in the main bed of the Most basin?

The paper deals with possibility of occurrence of volcanogenic interbeds in the main coal bed of the Most basin. Results of many used research methods, including thin cuts and borehole data, XRF and XRD analysis and field research did not confirm occurrence of volcanogenic interbeds. Thanks to this research, interesting geochemical and mineralogical anomalous layers were discovered marked by increased content of Sr, Ba, P and Ca elements mainly corresponding to crandallite minerals. In contrast to crandallite-bearing horizons in the overlying Libkovice layers, there were not found any connections with volcanogenic processes for these layers. Comparing...

The main target of this article to provide a contribution to the current discussion about possibilities of founding areas for natural succession in different types of localities. The research is based on comparison of long term survey of areas with different history of restoration and natural succession areas in the Most basin. The main attention is devoted to localities Radovesice and Střimice with long history of research. Based on the results of pedological survey, biological survey and survey of pollutants, the authors recommend to found succession areas only in suitable localities after detail mapping of every dump area without obligatory determined...
Complex information of outer dump sites - locality Velebudice

Zpravodaj Hnědé uhlí 2017, 57(2)
The article presents a summary of the available knowledge on the dump site Velebudice, mainly the development of hydrological and hydro-geological characteristics of the dump and their bottom, and information about the implemented rehabilitation actions. The entire article is divided into sections that contain a description of the original state before the dump site establishing, the history of mining activity impacts in the landscape, the characteristics of the material forming the dump and the ways of its creation. Further sections contains description of the development of the hydro-geological conditions of the dump body and its bottom and also...
