The main direction of laboratory research
Formation of the Central Asian School of Petrometallogenetics named after the founder of the laboratory, Academician Kh.M.Abdullaev. His classical works on Central Asian magmatism and metallogeny are based on the relationship of ore formation with magmatism, ore-petrographic series, division and classification of regions. The laboratory team has developed a theoretical basis for creating a metallogenic map of Central Asia. Scientific views on the genetic relationship of mineralization with magmatism and the multilevel nature of mineralization have been developed and substantiated. Issues related to the relationship of metallogeny with deeper parts of the earth’s crust, metallogenic specialization of various blocks of the lithosphere, and paleometallogenic aspects of the evolution of mining have been studied.
As a result of an in-depth study of ore deposits, their geological and genetic features and belonging to ore formations, the following important results were achieved: the discovery of a deposit of rare earth metals (lithium) of an unconventional type (Shavoz) (T. M. Voronich, L. M. Glazer); It is based on the fact that the southwestern Gissar is a new polymetallic pyrite region (Khandizinskoye deposit); The triangular barite-polymetallic deposit is of the stratiform type; a volcanogenic-sedimentary iron deposit (Temirkon) was discovered (P.V. Pankratev, Yu.V. Mikhailova); Unconventional types of complex mining of rare metals (niobium, tantalum, etc.) and rare earth metals associated with a new for the region ongonite-leucogranite association (U.D. Mamarozikov and others) have been identified.
Over the past 15 years of research conducted by the laboratory staff, the following important scientific and practical results have been achieved: For the first time in the Middle Tien Shan, new types of rare-metal acid igneous rocks have been identified – facies and curved ongonites, ongoryolites and leucogranites. Based on the study of their regional distribution in Eastern Uzbekistan, promising areas for rare and rare-earth metals, such as Karakushkhona-Boshkizilsoy, Chetsuv-Shavkatli, Ertoshsoy and Kelenchek-Toshsoy, were identified. Five facies types of genetically related mining operations have been identified with the ongoriolite-leucogranite association, which are based on the mechanisms of their formation: fluid-explosive-intrusive (Shavossoy type), exograizen (Sargardon type), apogranite-intrusive (Kelenchek-Toshsogyz-type-combination) and combination. (Chorkesar type). The results obtained were the basis for planning and effective conduct of special advance searches for rare-earth and rare-earth metals in the Kelenchek-Toshsai area. On the example of the Chestuv-Shavkatly ore field, a model of rare-earth and polygenic mineralization associated with plateau-like syenitoids and ongoryolite-leucogranite association was constructed. Very high concentrations of yttrium, scandium, and rare earth elements (922-2689 ppm) were found here in quartz-hematite-chlorite metasomatites and hydrothermalites (vessels) developed around the apophyses and apical parts of granosyenite and leucogranite intrusions. These postmagmatic products also contain high concentrations of tin, beryllium, zirconium, niobium, tantalum, tungsten, silver, thorium, and uranium. Based on the results obtained, it is recommended to conduct a special preliminary survey to assess the potential resources of the Chetsuv-Shavkatly area of rare earth metals of industrial importance, as well as noble and rare metal polymetallic ores. Niobium-tantalum pegmatites and greisens genetically related to the ongoriolite-leucogranite association of the Chorkesar region, rare-earth metallurgy of quartz-fluorocarbonate hydrothermal vessels, specialization of berisites for molybdenum and tungsten have been identified and substantiated. As a result, it was confirmed that the Chorkesar deposit is not only uranium-bearing, but also promising for rare metals (mainly niobium and tantalum) and rare earth metals. The material compositions and occurrences of about 50 types of peridotites of the gabbro-peridotite massifs of the Beltovsky (Taskazgonsky) and Severo-Tomditovsky, rock-forming and accessory-mineral minerals of gabbroids, and ore-forming fluid microforms were revealed. In particular, the main mineral concentrators and mineral carriers are iron, titanium, copper, nickel and cobalt, chromium, platinum, gold, silver, rare and rare earth metals, iron-chromium, iron-titanium and copper. -nickel can serve as a mineralogical criterion for determining mineralization. The study of these rocks was also carried out using the microprobe method, which revealed such microminerals as silicates, sulfates and carbonates of silver, palladium-silver, as well as light platinoids, fluids with gold and silver additives. The mass spectrometric studies of diabases and lamprophyres with ICP developed in Kulyuktov showed that the clarke concentrations of gold and silver-containing elements, such as arsenic, selenium, and lead, are several, or even ten, or even a hundred times higher than gold-silver. ore is made. This is confirmed by the microprobe detection of gold, silver, and light platinoids in pyrite and arsenopyrite in these rocks. It has been established that pulverized intrusive myaskite nepheline syenites and pegmatites are specialized in lithium, rubidium, cesium, zirconium and rare earth metals. These alkaline rocks are recommended to be evaluated as a promising complex raw material of universal aluminum-rare metal (Al, Li, Zr and TR). Laboratory staff:
