Insulation influence on the formation and location of rock crystal placers at the Southern Ural

Abstract

The paper deals with differences in valley density and quartz crystals concentration at buried Mesozoic and Oligocene depression slopes of different exposure. Considering some regularities of the present-day gullies formation and Oligocene and Miocene gully network the author came to the conclusion about rich crystal-bearing placers being situated at southfacing slopes of the depressions.
