    Ocena i wykorzystanie warunków środowiskowych w procesie wzbogacania kopaliny na drodze (bio)hydrometalurgicznej
    (Wydawnictwa AGH, 2010) Konopka, Elżbieta; Kisielowska, Ewa
    These are results of research on the possibility of enrichment uranium-bearing shales (black shales and walchia shales), which at a comparable, trace level of metal-bearing were strongly differed in their geochemical environments, which developed as a result of different compositions of microflora. Research was carried out on the dynamics of growth of micro-organisms most frequently represented in each of the geochemical environments and the associated with varying effectiveness of the leaching. It demonstrated that the enrichment of two radically different raw-shale materials using the biotechnical methods is possible, if taking into account every time changeable, individual and particular method, using the natural biogeochemical conditions of the raw material.

    Wstępne wyniki badań paleobotanicznych wiercenia Studzianna (trias-jura) z północnego obrzeżenia Gór Świętokrzyskich
    (Wydawnictwa AGH, 2009) Barbacka, Maria; Feldman-Olszewska, Anna; Jarzynka, Agata; Krupnik, Joanna; Ociepa, Anna Maria; Wcisło-Luraniec, Elżbieta; Ziaja, Jadwiga
    Studzianna well core (Triassic-Jurassic) from the Holy Cross Mts region were investigated. Fossil plants from the genus <i>Neocalamites</i> (Equisetales) were found mainly in the Triassic sediments. Fragments of Ginkgoales and Czekanowskiales and Coniferales were determined mainly from the Lower Jurassic. The Lower Jurassic microflora consists of sporomorphs from Bryophyta, Equisetales, Lycopodiales, Filicales from the family Cyatheaceae or Dicsoniaceae, Pteridospermophyta from Caytoniales, Ginkgoales or Cycadales or Bennettitales, Coniferales from the families Taxodiaceae, Pinaceae and Cheirolepidiaceae. Palynofacies have mainly terrestrial character and confirms earlier opinion (Karaszewski 1962, Pieńkowski 2004) of the prevailed terrestrial origin of the Lower Jurassic (Hettangian-Sinemurian) sediments from the Holy Cross Mts region.
