Metallogenic Specialization Of Sienitoid Small Intrusions And Dikes Of The Kumbel-Ugam Zone Of Depth Faults (Chatkal-Kurama Region, Middle Tian Shan)

The article describes the geological, petrographic, mineralogical and geochemical data confirming comagmatic nature of syenitoid small intrusions and dikes of the Kumbel-Ugam zone of deep faults. Specialty of syenitoids and related metasomatites and hydrothermalites for precious and rare metals is described on the basis of the results of microprobe analyzes of the forms of occurrence, the material composition of minerals, micro segregations of ore-bearing silicon-alkaline fluids and nanocrystallites in them. The results of mass-spectrometric study of syenitoids confirm their metallogenic specialization in noble, rare and rare earth metals.
