Abstract (english)

This presentation aims to demonstrate the appearance of nanosized and nanostructured mineral phases
determined in different modern marine and lacustrine sediments of the Adriatic region (Fig. 1) and in soils
situated on carbonate rocks along the Adriatic coast. Special attention was paid to determining the type of
nanominerals and nanosized mineral phases and their unique structural and morphological features at the
nanoscale. The results obtained show that their appearance in sediments and soils can be used to determine the
physico-chemical conditions that prevailed in the environment during their formation. In addition, the
occurrence of newly formed nanomineral particles allow us to determine the early diagenetically driven
changes that govern formation and phase transformation of nanosized mineral particles in environment. The
role of nanomineral phases in the cycling of trace elements in investigated sediments will be also addressed.
Biologically induced formation of submicron-sized, nanostructured and hierarchically organized biomineral
structures built up of anhydrous carbonates, particularly aragonite and calcite will be presented. Finally, the
role of reaffirmed non-classical crystal-growth mechanisms, especially the particle-mediated, nanoscale
aggregation route where nanostructured mineral phases are formed through the aggregation of preformed
nanosized particles will be discussed.
