According to foreign studies, significant (including industrial) concentrations of small and thin gold (STG) were found in quaternary sediments of syneclises and avlacogens of the East European platform. This allows us to hope for their detection within the southern frame of the Ukrainian shield and the northwestern black sea coast. Traditional practice did not allow to detect areas and types of precipitation with increased STG content, which is concentrated not in coarse clastic or psamite strata, but in pelite strata and could not be detected by the standard slice method. At the same time, the gold potential of the study area did not include information about the resources of STG due to the lack of effective methods of detection, study, enrichment and mining. Preliminary studies based on modern sampling and processing techniques revealed a number of points in cenozoic sedimentary rocks in southern ukraine with abnormally elevated alluvial STG content. Such STG placers in the cenozoic sedimentary cover can become an important resource for the formation of the gold mining industry in Ukraine. The general solution of the problem requires a systematic and methodologically sound study of distribution patterns, migration paths and conditions of STG localization.
