Abstract

Some results are given of laboratory experiments with rain simulator, aimed to tracing the correlation between the placer's structure and degree of erosion and the ore body configuration, the latter in some experiments was stock-like, in other- sill-like. Mineral amount in a placer as well as its granulometry appeared to manifest the relation between the degree of erosional cut-off and stages of the placer's evolution. The results obtained can be used for prediction of the ore body conservation on the basis of the placer's structure analysis.
