Popis | The provenance analyses of Permo- Carboniferous fl uvial sandstones of the Boskovice Basin and the Zöbing area are based on a wide spectra of analytical techniques (petrography, heavy mineral assemblages, chemistry of garnet, rutile and spinel, zircon study, major and trace elements). The studied sandstones are poorly sorted and reveal a relatively immature composition implying short distance transport, rapid deposition, a high-relief source area, prevailed physical weathering and the minor role of chemical weathering. |
