wAbstract
@Elemental compositions of the 2 mm fraction of three sediments
sampled along the Kupa River are presented. On plots of log (SiO2/Al2O3)
vs. log (CaO + Na2O)/K2O,
the sediments plot closest to average sandstone compositions.
On plots of weathering indices A vs. B (Kronberg and Nesbitt,
1981) the sediments plot close to basalt, terrestrial crust and
granite. X-ray diffraction of the 63Κm fraction suggests chlorite,
vermiculite and mica are present as weathering products in the
upper, middle and lower stream sediments. depletion of some elements
in the sediments suggests loss of elements from the sediments
due to dissolution of minerals/
