CHARACTERIZATION OF MICRON AND SUBMICRON-SIZED MINERAL PARTICLES FROM FOUR DISTINCT MARINE ENVIRONMENTS OF THE ADRIATIC SEA

Mineralogical, surface physico-chemical, morphological and structural characteristics of micron and submicron-sized mineral particles separated from different sedimentological environments of the eastern Adriatic coast were determined. The physicochemical characterization revealed a significant increase in cation exchange capacity (CEC) and specific surface area (SSA) with decreasing particle size. Mineralogical, morphological and structural analysis showed that the fractions with higher amount of aluminosilicate, oxide and oxyhydroxide particles exhibit significantly higher values of SSA and CEC, and consequently, increased reactivity of sediments in biogeochemical processes in the marine environment.
