ABSTRACT
Numerous Cu deposits of the Udokan-Chineysky ore district (Udokan deposit of cupriferous sandstones, deposits of the Chineysky pluton, etc.), which occur in sedimentary and igneous rocks, are similar in many genetic features. One of these features is the similar parameters of fluid inclusions (hydrothermal fluids) in quartz of the Udokan deposit, rich chalcopyrite ores from the Rudnyi (Rudnyie deposit, and veins of the Pravoingamakitsky deposit studied previously. Fluid inclusions have the same range of high salinity and homogenization temperatures. These studies combined with geological data allow us to consider the formation of contact sulfide ores from the Chineisky pluton and Pravoingamakitsky and Udokan deposits as a common compound fluid-magmatic ore-generating system. The sedimentary rocks primarily enriched in chalcopyrite, pyrite, and pyrrhotite of the entire section of the Udokan complex served as the host media for the hydrothermal fluids and deposits of various scales.

    Extensive mafic sills known as the Umkondo dolerites intrude sedimentary strata of the Umkondo Group, which overlie the eastern margin of the Archaean Zimbabwe craton. Zircons and composite baddeleyite-zircon crystals were recovered from a sample of coarse-grained felsic gabbro collected near...
