New data on the origin of the Fe-Cu-As skarn deposit at Obří důl, West Sudetes, Bohemian Massif

The Obří důl Fe-Cu-As sulfide deposit is hosted in metamorphosed lenses of marble, calc-silicate rocks and skarns. The deposit is located up to a few hundred meters away from the contact of the large, late-orogenic Variscan Krkonoše-Jizera Plutonic Complex (KJPC). Mineralogical and fluid inclusion studies of the Gustavská ore lens show that the main sulfide stage, dominated by pyrrhotite, chalcopyrite and arsenopyrite, originated from water-rich hydrothermal fluids with salinities up to 8 wt.% NaCl eq. at temperatures ranging from 324 to 358°C.These fluids replaced mainly the carbonate-rich lithologies. The 34S values indicate a magmatic source of sulfur and Re/Os dating of molybdenite are consistent with simultaneous formation of the main sulfide stage ore and the KJPC.
Petrology of differentiated alkaline, high-level intrusive bodies in the Zahořany - Chotiněves belt
Mysliveček, Jakub ; Verner, Kryštof (advisor) ; Erban, Vojtěch (referee)
The aim of the work was petrological research focused on alkaline volcanic bodies in line between villages Zahořany - Chotiněves near Litoměřice. Part of the area is covered by Tertiary volcanism products, which affected large parts of Europe and in our territory extends in the form of extensional structure of Ohře rift. The Field of studied objects is located nearby the southern edge of České středohoří vulcanic complex and the northern edge of the Central Volcanic Field. The question was whether studied area belongs, if it's still České středohoří volcanic complex or it belongs to Central Bohemian volcanic field. The area was visited several times for determinate the volcanic bodies and have been identified six localities which were collected rock samples for geochemical analysis and Probe Micro Analysis. Also, the detailed mapping of the bodies and their spatial extensions was performed because currently available geological map of 1: 50 000 do not correspond to reality. The area is situated close to Litoměřice break, which probably caused the linear distribution of magma in the direction of fracture, approximately NE - SW. Studied rocks by the classification TAS are classified as basaltic trachyandesites and are mainly composed by plagioclase, clinopyroxene, magnetite and to a small extent from biotite...
Rites and festivals of contemporary local cultures
Válková, Jana ; Soukup, Václav (advisor) ; Soukup, Martin (referee) ; Erban, Vít (referee)
The study eoneerns theoretie and empirieal analysis of festivities and rites including their influenee on eontemporary human existence. The researeh is foeused on reeent loeal cultures. The interdisdplinary and holistic approaeh is joining up the study of the problem both in terms of individuals, their families and loeal sodety, whieh enables to unravel and interpret the eonnections between festivals and the sodo-eultural system as sueh. Therefore, the thesis is based on theoretieal analysis, including spedal literature analysis, as well as on field researeh of partieular loeal eultures. Empirieal researeh notes down partieular festivals and rites as observed in three reeent loeal eultures of the Czeeh Republie: Nové Sady (near Velká Bíteš, in the district of Žďár nad Sázavou and Vysočina Region), Hrubý Jeseník (in the district of Nymburk and Central Bohemia region) and Radim u Jičína (in the district of Jičín and Hradec Králové Region). The field researeh took plaee from 2004 to 2010, the terrains have not been studied before.
