Abstract
~ ~ ~ Data of isotope geochronological researches of zircons by U-Pb method, also results of Ar-Ar method researches of muscovites from the gold-bearing ores, surrounding schists and granites of the Panimba gold deposit in the Yenisey Ridge are presented. Regional metamorphism of the lower Riphean Kordinskaya suite terrigene sediments, containing ore bodies, took place in the interval of 996,0±32 - 889,0±26,6 Ma. The graniteforming and contact metamorphism of schists in the ore field of the mineral deposit have occurred on a boundary of 868,9±6,5 Ma. The absolute age of the quartz gold sulphide orebearing veins lies in the interval of 817,2±5,3 - 744±17 Ma (by muscovite with Ar-Ar method) and 815,0±37,6 - 762,3±33,3 Ma (by zircon from ore schists with U-Pb method). The long history of development of the Yenisei Range from Upper Archean to Upper Paleozoic was reflected in an accessory zircon of ore schists.
