Geochemical characteristics of silty clays from the Brusartsi Formation

Abstract

This study investigated the geochemical characteristics of Pliocene clay sediments from the Brusartsi Formation, situated in the area of the town of Kozloduy, North Bulgaria). The main objective of the study is to characterize the Brusartsi clays as a natural barrier against pollutant and radionuclide migration. Based on mineralogical and geochemical analyses, new results are obtained concerning the mineral composition, cation exchange capacity (CEC), specific surface area, etc., for the Brusartsi Formation.
