The article describes the results of petrographical and petrochemical studies of ultrabasites and basites of the Teskuduk-Chengeldi massif of the Northern Tamdytau (Western Tien Shan). The main minerals-carriers and minerals-concentrators of chromium, nickel and cobalt, platinoids, gold, silver and rare-earth metals are determined. Using the mass-spectrometric analysis (ICP-MS), a geochemical characterization of the rocks of the massif was obtained and their specialization in chromium, nickel and cobalt was confirmed. The contents of gold, silver, and related elements (Se, Sb, Te, As, Bi) increasing from peridotites to gabbroids and their derivatives. The conclusion is made about the formation of the ore-magmatic system of the Teskuduk-Chengeldi massif under spreading conditions, the evolution of which formed chrome-nickel mineralization with platinum and gold-silver loading.
