Silicified stems of upper Paleozoic plants from the Intra Sudetic and Krkonoše Piedmont basins
Mencl, Václav ; Sakala, Jakub (advisor) ; Pšenička, Josef (referee) ; Florjan, Slawomir (referee)
The late Paleozoic deposits of the Czech Republic are famous for their rich occurence of silicified stems. Despite the fact they have been often described and are well-known among scientists and collectors, their modern evaluation is lacking. This work summarizes results of recent anatomical and paleoenvironmental studies of silicified stems of the Intra Sudetic and Krkonoše Piedmont basins, where are these fossils found very frequently. Based on field research and review of public and private collections, the presence of silicified remnants was proved in several stratigraphic units. Firstly, this work deals with silicified stems of calamitaleans, which are known from the Ploužnice Horizon of the Krkonoše Piedmont Basin, and some gymnosperms. Based on anatomical studies of the secondary xylem and other related features there were found two species of calamitaleans: Arthropitys cf. bistriata and Calamitea striata. Secondly, the more abundant Agathoxylon - type of wood was divided into two groups, which are assigned to cordaitaleans, and conifers. The palaeoenvironmental conditions were partly reconstructed according to sedimentary structures and also according to cordaitaleans - conifers ratio in each wood-bearing layer.

Vnitrosudetská pánev: Pasportizace geologických vrtů
Hydrogeologická společnost, Praha ; Korošová, Zuzana ; Adamcová, Anna ; Králová, Lada ; Kněžek, Vojtěch ; Koroš, Ivan
V rámci česko-polské spolupráce jsou řešeny úkoly vyplývající z potřeby reálně popsat procesy srážkotvorného režimu v oblasti vnitrosudetské pánve, která je přeshraničním vodním útvarem podzemních vod. Předkládané práce zohledňují požadavky na kompatibilitu českých a polských pasportů. Jsou popsány objekty v příhraniční oblasti Police nad Metují - Kudowa Zdrój (OPKu), Krzeszów - Adršpach (OKrA) a povodí horní a střední Stěnavy (OS). Proběhlo terénní zaměření a popis 26 objektů české části monitorovací sítě hraničních vod. Byly vypracovány pasporty hydrogeologických objektů české části monitorovací sítě.
