The major and trace element chemical composition of Neoproterozoic shales from the Kalius Member, Nagoriany Formation has been investigated to determine the source-area rock composition and paleo-weathering conditions during the Late Proterozoic. The different bivariate plots suggest their derivation from predominantly felsic source-area rocks and partially from basic source-area rocks. The paleo-weathering data indicate that during the sedimentation of the Kalius shales the source-area rocks were moderately weathered. |
