Radiochemical and geochemical studies of the seafloor massive sulfides (SMS) from the «Zenith-Vic- tory» hydrothermal field within the Mid-Atlantic Ridge were carried out. The data on specific activities and distribution of the 238U, 234U, 232Th, 230Th isotopes, their activity ratios and ages of the analyzed samples were obtained. Our experimental results and published data provide evidence that 230Th/U dating yield reliable dates of the ore formation. The total age range of the SMS deposits is no less than ~59.5 kyr. There are at least three stages in the formation of ores having different geochemical specialization. Structural and matter characteristics and relationships of ore minerals in the SMS deposits from the «Zenith-Victoria» field allow us to outline the following sequences of their formation within each separate stage: firstly, Fe-S ore, secondly, Cu-Fe ore, and, finally, Zn-Fe ore. According to our data, the first stage finished about 59,5 kyr ago with the Zn-Fe ore formation. The second stage includes two major episodes of the Fe-S ore formation in the range of approx. 43,5-34,5 kyr ago and the Cu-Fe ore formation approx. 29,9-20,7 kyr ago. The third, and final, stage includes the consecutive steps of ore formation in the range of approx. 17,1-2,1 kyr ago for the Fe-S ores, approx. 2,1-0,5 kyr ago for the Cu-Fe ores, and the Zn-Fe ores are forming at the present time. The geo-chronological and geo-chemical data currently available do not allow to fully and unambiguously specify the proposed stages of ore formation within the studied field. From this point of view, the comprehensive studies of both sulphide ores and metalliferous sediments associated with them and formed in the distal areas of the «Zenith-Victoria» ore field must be of considerable scientific interest in the future.
