Abstract - Summary 
(short description):
Summary. Geological, petrographic, petrochemical and geochemical data and the results of isotope rubidium-strontium studies of the rocks of injection-explosive, subvolcanic bodies, dikes, necks, multi-level sills and stocks of Chatkal-Kurama ore region are presented. A new explosive-extrusive model of Shavaz type lithium mineralization formation is given. It is suggested that fluid saturated subalkalic ongorhyolite melt were the source of rare metals. Alkaline ongorhyolites of Yertashsay melt has been saturated by fluids (especially by fluorine) and enriched by Ti, W, Mo, Sn, Nb, Ta, Zr, Hf, radioactive and rare earth elements. The origin of magma of these formations has been explained from position of metamagmatism. The genetic connection of rare metal ore bearing body of leucogranites in Sargardon and Kelenchek ore deposits is established. The nature of ore-bearing, saturated with fluorine melt leucogranites is mixed, mantle-earth crust. In intra-plate stage (1-2) was formed ongorhyolite-leycogranite series. They are connected with fluidizate-explosive (Shavazsay), extrusive-intrusive (Yertashsay), exogreisens (Sargardon) and albititic (Kelenchek) types of complex rare-metallic (W, Sn, Mo, Nb, Ta, TR etc.) ore deposits of Eastern Uzbekistan.
