ESPECIALLY OF SMALL AND DISPERSED GOLD FROM SEDIMENTARY ROCKS OF THE LOWER DNIEPER REGION 
The new data on mineralogy of fine gold in sediments of the Lower Dnieper are obtained. General regularities of distribution of gold and satellite minerals in section and all over the area are established. Features of composition, morphology and internal structure of gold particles indicate the gold entering from various sources and participation of diagenetic transformations of deposit in forming associations and paragenesis with gold. Necessity in improvement of prospecting method and extraction technology of fine gold from placer deposits in the south of Ukraine is grounded. 
Key words: alluvium, fine gold, sulphides, diagenesis, indicators of mineralization.
