Abstract

In this study surface sediments of the Croatian part of the Adriatic sea have been investigated. Granulometric data were gained by wet sieving and with the sedigraph. Carbonate component was determined by calcimetry. Fraction <2μm was analysed by X-ray diffraction. Most of the sediments are muds, which was excepted considering that samples were taken from the areas where the previous research determined a larger share of the mud fraction. Calcimetry has proved a significant proportion of carbonate in the fine-grain fraction, which are different from previous reviews that the fine-grain fraction is siliciclastic. The rest of the fine grain fraction consists of clay minerals that are represented with minerals illite, smectite, chlorite, kaolinite and in some samples with serpentine. Differences in "crystallinity" of illite and smectite made it possible to more clearly differentiate sedimentary areas of the Croatian side. All data were compared with data obtained by previous research on the Italian side. This research has helped to upgrade the current image of the sedimentary area of the Adriatic
