| Abstract: | Clastic gold in the Cenozoic sediments of the Ural Foredeep is referred to the apron and aureole dynamic types of alluvial placers, which are formed at a distance of 10–30 km from their sources. The gold grains vary appreciably in size and chemical composition of individuals and are characterized by good round-ness and high degree of alluvial refining. It is suggested that endogenic gold occurrences in mountainous regions of the Polar and Subpolar Urals were the main sources of clastic gold grains. |
