Ancient placers at the Upper Kolyma Highland

Abstract

The author considers gold placers to be ancient if they are relict regarding to the modern geomorphological process of the relief's elements. Some inherited valleys of the Upper Kolyma Highland being taken as an example, the ancient gold placers are proved to be in historical-genetic connection with Neogene erosional surface cutting the previous sedimentary zones and the crusts of weathering. The geomorphological position of gold placers is determined by the pattern of the Neogene surface dissection in process of the neotectonic activization.
