COLLECTION OF SCIENTIFIC WORKS OF THE IGS NAS OF UKRAINE, VOL. 8, 2015 INTRODUCTION The presence of fine gold in bottom sediments is a characteristic feature for the Northwestern Black Sea shelf (Shnyukov, Ziborov, 2004, Shnyukov, 2001). Accumulation of gold particles takes place in different facial environments on the shelf (Fedoronchuk et al., 2013) as well as in various terrigenousmineralogical areas and there is no dominant source of nourishment of fine gold. Fine gold has different origin and its distribution has extremely irregular character in bottom deposits (Reznik, Fedoronchuk, 2000, Ivanova et al., 2006, Fedoronchuk, Suchkov, 2012, Fedoronchuk, 2001, Yushin, 2009). As it was noted in previous research (Reznik, 1999, 2003, Fedoronchuk, 2001) fine gold has a tendency to accumulate in sediments with poor sorting and which consist of terrigenous and biogenic components, for example in muddy, silty and sandy shell deposits. However there is no obvious dependence between gold content and certain components of sediments. Unevenness of distribution and different origin of fine gold make it complicated to reveal clear patterns of accumulation in the bottom deposits. This paper focuses on the study of fine gold particles distribution within different areas in the Northwestern Black Sea shelf. The highest concentrations of fine gold are observed in Dnieper depression, in the vicinity of Tendra spit, Zhebriyany bay and Zmeiniy Island area (Reznik, 2003, Fedoronchuk et al., 2001).
