Abstract

The paper considers the mechanizm of alluvial placers formation, which are located in buried valleys on a structure's wings. The metal particles accumulation in placer is mostly controlled by differences in the channel process upstream and downstream of the growing structure; the channel within the limits of the structure itself is distinguished by a chord-like profile, typical for growing structures. The rate of structures's wings uplift determines also the preservation of metal-bearing layers formed in the past at different-stages of the relief's evolution. - (L'A.)
