Fluorite mineralization of the Ohře Graben and comparison with similar deposit types worldwide.
Markes, Jan ; Zachariáš, Jiří (advisor) ; Přikryl, Richard (referee)
SUMMARY: The thesis is concerned with fluid inclusions of fluorite deposits in Vrchoslav, summarizes the findings of the genesis of fluorite deposits in general and compares them with deposits of Ohře Rift.. Fluorite is an essential mineral that is used in industry as a raw material for the manufacture of plastics, liquids to transfer the cold, hydrofluoric acid, it is also used in metallurgy, glassmaking and clear crystals in optics.

Západní část Oháreckého riftu – vliv plášťových hranic paleodesek na povrchovou tektoniku
Babuška, Vladislav ; Plomerová, Jaroslava ; Achauer, U. ; Vecsey, Luděk
Boundaries of blocks of the mantle lithosphere, with a fabric modelled from seismic anisotropy, predestined locations of the Eger Rift, Cheb Basin, Quaternary volcanoes, crustal earthquake swarms and exhalation centers of CO2 and 3He of mantle origin.
Cenozoické vulkanické série v západní části Českého masívu
Ulrych, Jaromír ; Novák, Jiří Karel ; Lloyd, F. E. ; Balogh, K. ; Hegner, E. ; Viereck-Götte, L. G.
The western part of the Ohře/Eger Rift is a geodynamically active area in the Alpine foreland. Associated Cenozoic alkaline volcanism, particularly that of Quaternary age, plays an important role in the seismic active region of the W Bohemia and Saxony and is accompanied by intensive manifestations of mantle degassing (CO2, He, N). Three Tertiary to Quaternary alkaline volcanic rock series were recognised there: 1. Early Oligocene to Early Miocene (31-20 Ma) in the Doupovské hory Mts. and western Ohře Riftu. 2. Middle to Late Miocene (16-8 Ma) associated with the Cheb-Domažlice Graben. 3. Pleistocene (0.43-0.26/0.11 Ma) associated with the Ohře Rift and Cheb-Domažlice Graben junction. On the basis of isotopic and geochemical data of the primitive mafic volcanics of all series the source of magmas is a sublithospheric HIMU mantle source.
