Abstract

For the Dzhimidonsky vein polymetallic deposit (North Ossetia, Russia), formed in the Middle Jurassic time, it was established by the nature of the distribution of rare-earth elements in the veins and rocks that the sources of REE and ore components were a combination of host rocks of different composition (PR3–PZ1, PZ3) and were replaced in time. Geochemical data served as the basis for the development of new methods of equilibrium-dynamic modeling and assessment of the influence of the change in time and space of fluid flows from different sources on the processes of ore formation.
