Abstract

Different-aged (from recent to Paleozoic ones) fluvial valley and channel systems are collectors for mineral deposits of wide spectrum: from distal gravitational accumulations (placers of Au, PGE, Sn) through proximal placers (diamond, heavy minerals, and finegrained gold) to leached deposits on complex geochemical barriers (U, Mo, TR). The wide tectonic diversity in the Eurasia North (cratons, different-aged plates and erogenic belts) allows to compare styles of palaeovalley and palaeochannel minerageny according to the type of the Earth crust.
