Pre-Dobrudgian depression was thougth the area of unknown perspective to cooper-bearing. For the first time detailed litogeochemical research of the Pre-Dobrudgian depression upper-jurassic redcolour-terrigenous subformation are carried out according to kinds of rocks, taking into consideration the physical and chemical conditions of the geological environment and processes of gleization. The basic attention was given to research of copper-bearing potential of the subformation. It is ascertained that the physical and chemical conditions of forming of sedimentations of Chadyr-Lunga suite did not promout the concentration of copper in sulfide form. A copper in the subformation of tithonian is in the dissipated state and nebulized in the rocks (both for lateral and in the cut). The physico-chemical conditions of forming of this rocks as well as gleization of them didn’t a work upon the re-distribution of copper in them greatly.
Founding on the conducted researches, it is ascertained that general cooper-bearing potential of upper-jurassiс lagoon redcolour-terrigenous subformation is compared with such for the continental low-devonian redcolour-terrigenous formation of Volyno-Podolia and marine redcolour-terrigenous subformation of Neogene of Pre-Carpathian sag, which are perspective from the point of view of general estimation of potential of copper-bearing of redcolour formational units of Ukraine. The conducted researches allowed to take upper-jurassiс lagoon redcolour-terrigenous subformation to cooper-bearing structure units of Ukraine.
