Distribution of fine gold in paleovalley deposits of Voronezh Anteclise.
Increased gold content (up to 5.64g/t) of the sedimentary cover is discovered in many sections of Cretaceous and Cenozoic sediments of the region. In order to find the regularity in distribution of ultrafine metal (with prevalent gold particle size of 25-75mcm) the detailed sampling of the sedimentary filling of newly-discovered ancient cuts -paleovalleys was made. The impact of gravity factor on the formation of rock intervals enriched by ultrafine «floating» gold is established, as well as some differences in this process from traditional placers.
