Synopsis top ↑

The jubilee volume 25 of Krystalinikum is dedicated to the founder and many years' editor of this miscellany, RNDr Arnost Dudek, DrSc.

According to the main professional orientation of A. Dudek, the present volume deals with basic and ultrabasic eruptive rocks and their metamorphosed equivalents especially from the area of the Bohemian Massif. J. Baburek describes the genetic relationships of basic and ultrabasic rocks on the border of Bohemicum and Moldanubicum (Neukirchen-Kdyne Massif). V. Ledvinkova et al. deal with the ultrabasic rock from the Sazava tonalite in the central-Bohemian pluton which is similar to the rocks of the Jilove-zone, whereas the other numerous inclusions in tonalite posess petrological relations rather with Cambrian volcanic rocks of the Bohemicum. D. Nemec together with P. Sulovsky interpret the amphibolites of the Moravian Moldanubicum as spread ofiolites and D. Nemec analyses in great detail the changes in their composition after the metamorphosis. This topic is also dealt with by O. Moravcova who proves a rather conservative character of their metamorphosis. Nemeckova et al. worked on the garnet amphibolites in units linking up with the Moravicum and Yaxley and Klapova examine the conditions of the origin of eclogites with carbonates in Saxonthuringicum.

The other articles correspond to the professional interests of A. Dudek as well Granite from Rochovce (Veporicum) is, according to the statement of Hrasek et al., of upper-cretaceous age. Alcalic basaltoids (basanites and alcalic lamprohyres of cretaceous age formed, according to Hovorka et al., an independent volcanic unit in the Western Carpathians similar to basalts of the ocean islands which came into being through a passive rise of melts in an extending tectonic regime.
