Металлоносные конгломераты — потенциальные источники россыпей в Арктической зоне России

Abstract

Using the example of four large regions of the Arctic zone of Russia, the authors show the wide development of potentially metalliferous conglomerates of various ages, composition, stratigraphic and structural positions. Information on the metal content of the Precambrian conglomerates of the Kola Peninsula and the Anabar Shield is extremely limited. The metal content of the Precambrian conglomerates is well studied only in the Vetreny Belt in the Arkhangelsk Region. The revealed geochemical features reflect the lithological and mineral composition of the conglomerates. Small and medium-scale industrial placers of gold and platinum, other strategic minerals and their placers mark the areas of the Paleozoic and Mesozoic conglomerates within the Taimyr-Severozemelskaya Province and in the Pekulney-Zolotogorsky district of Eastern Chukotka. The authors indicate the prospects for the development of the mineral resource base of placer deposits.
