(North-Eastern federal university) // solov_@rambler.ru ОROGENIC GOLD DEPOSITS WITH SIGNIFICANT RESOURCE POTENTIAL OF CENTRAL PART OF THE YANA-KOLYMA BELT The results of integrated geologic-structural, lithologic-geochemical, mineralogic exploration of gold deposits of the Taryn ore cluster, located in central part of the Yana-Kolyma belt are given. Ore-bearing rocks were formed in the environment of passive continental margin, in unstable conditions, in the basin with strongly marked redox conditions. Systems of concordant thrusts and transverse faults, closely associated with them are the major ore-controlling structures. Several types of mineralization are manifested (from early to later ones): orogenic (metamorphogenic-hydrothermal, gold-quartz low-sulfide, gold-bismuth) and post-accretional (berthierite-antimonite and silver-antimony). Connection between mineral types of mineralization and stages of geodynamic development of the area is found.
