Petrology Laboratory

The history of the laboratory

The laboratory has been conducting fundamental and applied research since the establishment of the institute.

Heads of the laboratory: I.M. Isamukhamedov (1938-1957), Corresponding Member of the Academy of Sciences of the Republic of Uzbekistan; Academician I.Kh.Khamrabaev (1958-2002), D.Sc. (Geol.-Min.); R.Akhundzhanov (2003-2020), D.Sc. (PhD), Senior Researcher; Karimova F.B. (since 2021). The main scientific directions of the laboratory are the study of igneous and metamorphic rocks and determination of the conditions of their formation; studies of the evolution of magmatism, composition, structure of the earth’s crust; development of petrological models for the formation of endogenous deposits.

The main goal and objectives of the research carried out by the petrology laboratory

Dismemberment of igneous, metamorphic and metasomatic formations of the republic’s territory on a geodynamic basis (identification of petrogenetic types). Ore-bearing capacity of magmatism of ore regions covered by sedimentary complexes. Formational analysis and metallogeny of ultramafic, mafic, gabbro-monzonite-syenite and granitoid rock associations.

Development of criteria for ore-bearing capacity of igneous, metamorphic and metasomatic formations. It is known from numerous works that there are geochemical, mineralogical, petrochemical and petrographic signs of productivity of igneous, metamorphic and metasomatic complexes into certain types of mineralization, but many of them have not yet been identified.

Study of ultrabasite-basite magmatism, granitoid and related mineralization, which are widespread within the Republic. The problem is aimed at identifying the causes of origin and modeling the evolution of ultrabasite-basite and granitoid magmas, up to the formation of related deposits of Fe, Ti, Mn, Cr, Cu, Au, Ag, platinum group metals, rare, rare earth and other metals. Petrologists have not revealed the nature of the relationship between various mechanisms of basaltic magma formation and the diversity of their types and metallogenic specialization.

Study of the petrology of various dikes in the mining regions of Uzbekistan and determination of their petro- and ore-generating role in the formation of ore minerals, as well as identification of levels of magma formation centers, sources of endogenous mineralization and their relationship with deep geodynamic phenomena.

The study of Precambrian magmatism of the Western Tien Shan (age, ore content, genesis), determination of the role of pre-Paleozoic magmatism, metamorphism and metasomatism in the formation and development of the continental crust and ore formation is the most important problem of petrology.

Petrology of metamorphic formations and precious metal mineralization of the Central Kyzylkum, identification of patterns of metamorphism to clarify the genesis of precious metal mineralization and the nature of its distribution in the Central Kyzylkum region.

Currently, the petrology laboratory has 10 employees, including 1 professor, 2 doctors of science, 2 candidates of science, 2 doctoral students, 2 engineer-geologists. Research on the problem of magmatism and its connection with mineralization dates back to the founding of the institute and is still one of its main priorities.
