Presented here are the results of the study of surface (hypergenous) migration of a number of chemical elements in a swampy area of the northwestern Siberian Platform. The migration mode of a number of chemical elements, and their relationship with the ore bodies, were determined from a study of various natural objects (water, peat, iron gels, etc.). Geochemical exploration criteria for the bornite-chalcocite ores are cited. - Author.
