Abstract

Phase forms of gold in the ore bodies, crust of weathering and residual-talus accumulations of secondary dispersion halo have been studied in the objects of the Polar Urals and Yenissey Ridge. Within the overlapped areas of sulfur-bearing and low-sulfur gold ore objects, the model of Au phase forms redistribution in the system of 'ore body - secondary dispersion pattern' in the abnormal geochemical fields interpretations has been suggested. It has been found out that within the ore zones, located directly over the ore bodies, both granular and sorption-type forms of gold in the residual soils are present. As the distance from the ore body increases, the number of sorption-type forms of gold gradually rises as well, whereas beyond the ore field talus deposits contain solely xenogeneic granular particles of gold.
