Indium in the environment
Kulakowski, Ondřej ; Drahota, Petr (advisor) ; Filippi, Michal (referee)
This bachelor thesis is focused on the presence, bonds and concentration of indium in various spheres of the environment. It presents a comprehensive overview of the distribution of indium in rocks, waters, air and organisms, its concentrations, speciation, mobility and refers to its toxicity. It also provides the basic physical and chemical properties of indium and its compounds, mineralogy and geochemistry. The major Czech and world deposits are reported. At the end it devotes significant world producers of indium, and also mentions recycling procedures of this element. Powered by TCPDF (www.tcpdf.org)

16th International Congress of Speleology : Czech Republic, Brno July 21–28,2013 : proceedings
Filippi, Michal ; Bosák, Pavel
Proceedings of the 16th International Congress of Speleology consist of 3 separate Volumes. The Congress was visited by 1007 participants from 53 countries across the world. Volume III also starts with traditional, heavily attended topics organized in two sessions: “Karst and Caves in Carbonate Rocks, Salt and Gypsum” and “Karst and Caves in Other Rocks, Pseudokarst”. These topics are supplemented by the related session “Speleogenesis”. This last volume of the Proceedings is ended by the study of cave minerals, included in a specific session “Cave Minerals”.

16th International Congress of Speleology : Czech Republic, Brno July 21–28,2013 : proceedings
Filippi, Michal ; Bosák, Pavel
Proceedings of the 16th International Congress of Speleology consist of 3 separate Volumes. The Congress was visited by 1007 participants from 53 countries across the world. Volume I starts with three plenary lectures representing three global cave and karst topics. Further it contains papers concerned with history of research, archeology, paleontology, topics focused on management and preservation of caves and karst areas and other social-related aspects and also it contains a small part devoted to extraterrestrial karst. Volume I is ended by a large portion of biology-oriented papers.

Na Javorce Cave - a new discovery in the Bohemian Karst (Czech Republic): unique example of relationships between hydrothermal and common karstification.
Dragoun, J. ; Žák, Karel ; Vejlupek, J. ; Filippi, Michal ; Novotný, J. ; Dobeš, J.
The Na Javorce Cave is located in the Bohemian Karst, Czech Republic, about 25 km SW of Prague. The cave was formed in vertically dipping layers of Lower Devonian limestone; it is 1,723 m long and 129 m deep, of which 9 m is permanently flooded. The cave is polygenetic, with several clearly separable evolutionary stages. Cavities discovered to date were mostly formed along the tectonic structures of two main systems. One of these systems is represented by vertical faults of generally N-S strike, which are frequently accompanied by vein hydrothermal calcite with crystal cavities. The second fault system is represented by moderately inclined west-dipping faults. Smaller tube-like passages of phreatic morphology connect the larger cavities. The fluid inclusion data obtained for calcite developed along both fault systems in combination with C and O stable isotope studies indicate that the hydrothermal calcite was deposited from moderately NaCl-type basinal fluids (0.5 to 8.7 wt. % NaCl equ

Project Namak: some of the most spectacular findings in the Iranian salt karst
Filippi, Michal ; Bruthans, J. ; Jager, O. ; Zare, M. ; Asadi, N.
Project (“namak” means salt in Persian language) is an informal association of geologists and speleologists who cooperate on exploration and scientific research of the salt karst in southern and southwestern Iran. During the Project(from 1998 until 2013) about 16 salt diapirs were visited and more than 60 caves were discovered, 30 of which were mapped. The most exciting scientific and speleological discoveries were made in the Namakdan, Hormoz and Jahani salt diapirs; however, many other remarkable discoveries have been made on other several Iranian salt diapirs. This contribution summarizes the most interesting findings achieved during the ten expeditions carried out by the NAMAK team.
