Tishchenko A. Mineralogy of native metals from the kimberlites and lamproites of Ukraine

The dissertation deals with the research of auriferous and mineralogy of native metals from the kimberlites and lamproites of Ukraine (the Azov Sea area and Kirovograd district) with the use of comparative material on mineralogy of native metals from kimberlites, lamproites and other alkaline-ultrabasitic rocks of volcanic pipes and products from technological enrichment of the Sakha (Yakutia), Belarus and China. As a result of conduced researches of the Azov Sea area and Kirovograd district there were fixed various in morphology and different in composition minerals of native metals. Native copper and gold are the most widespread, the finds of avaruite, native aluminium, zinc, lead, platinum iridium, tin, highly mercury and copper gold, natural disordered alloys of copper-zinc-tin- and tin-lead-antimony-copper are single. Study of the morphology and chemical composition of the discovered native metal phases in the alkaline-ultrabasitic rocks of Ukraine, Yakutia, China and Belarus showed their different genetic nature. Parts of minerals of native metals are magmatic formations (avaruite, spherical exhaletion of pure copper and different composition of gold, platinum iridium), the most part of them connected with auto- and posthydrothermal transformations of the included rocks with the participations of the natural restoratives.
