The areas of use of lead, zinc and silver are very different. Lead is widely used in the electrical industry, especially for the manufacture of batteries and cable tubes, is used in the aircraft and radio industries, and in mechanical engineering. Keywords: search for polymetallic mineralization. ГЕОЛОГИЯ, ПОИСКИ И РАЗВЕДКА ТВЕРДЫХ ПОЛЕЗНЫХ ИСКОПАЕМЫХ, МИНЕРАГЕНИЯ. Аннотация. Области применения свинца, цинка и серебра весьма разнообразны. Свинец широко применяется в электротехнической промышленности, особенно для изготовления аккумуляторов и кабельных трубок, применяется в авиационной и радиопромышленности, в машиностроении. Ключевые слова: поиск полиметаллического оруденения. Relevance of the research topic. Among other types of minerals, polymetallic (lead-zinc) deposits in Tajikistan are of particular importance. Almost all objects of this mineral in Northern Tajikistan, including Western Karamazar (Takeli and Kansai ore fields) are silver-bearing. This determines the relevance of the research topic. In this regard, a more in-depth study of lead-zinc objects is of great practical and theoretical importance. The areas of use for lead, zinc and silver are very different. Lead is widely used in the electrical industry, especially for the manufacture of batteries and cable tubes, is used in the aircraft and radio industries, and in mechanical engineering. Because of its ability to absorb X-rays, it is used as protective screens. Paints are also prepared from it, lead oxide is used in metallurgy, glass making and medicine. Zinc is used for the production of galvanized iron, goes to the preparation of brass, bronze, cupronickel and other alloys, in mechanical engineering, the electrical industry, metallurgy, medicine and other sectors of the national economy. Silver is used mainly in the radio- electronic, electrical, food industries, medicine, nanotechnology, as well as in the form of alloys (coins are minted from them, jewelry and household products, laboratory and tableware are made), etc. The widespread use of these metals in the national economy determines the need for prospecting, exploration and production of polymetal deposits. Research objectives. To achieve this goal, the following tasks were envisaged: a detailed study of the mineral composition of individual ore bodies and deposits of the Takeli and Kansai ore fields as a whole, especially silver mineralization, to identify the typomorphic features of individual minerals or mineral paragenetic associations, and to establish the staging of hydrothermal mineralization. The degree of scientific development of the problem under study. Studies of the ore content of Karamazar have a long history. The mining industry reached its peak in the Middle Ages (VIII-XII centuries). Numerous mine workings of that time at the Kansai, Jerkamar, Takeli and other deposits testify to this. However, information on the conduct of scientific research at that time is very scarce. After a long break (until the end of the 19th century), we find the first 2 52 International scientific journal ISSN: 2181-3906 «MODERN SCIENCE АND RESEARCH» 2023 VOLUME 2 / ISSUE 3 / UIF:8.2 / MODERNSCIENCE.UZ information about the ore content of Kansai in the works of G.D. Romanovsky. At the beginning of the 20th century, V.N. Tomilin and A.A. Andreev, summarizing the available information, compile a catalog of the minerals of Turkestan. The systematic study of the Western Karamazar begins in 1925-1927. At this time, they begin a detailed geological study and exploration work, and already in 1931, the Kansai, Dagani Darbaza and Takeli deposits begin to be developed. In the future, many researchers began to study the deposits of the Western Karamazar, such as I.V. Dyugaev, B.N. Nasledov, A.V. Korolev, F.Ch. Ziyaev, F.I. Wolfson, Z.A. Koroleva, E.D. Karpova, Kh.M. Abdullaev, Z.M. Protodyakonova, I.V. Dubrova, A.A. Filimonova, V.A. Zharikov, Z.M. Protodyakonov and V.S. Popov. The works of these researchers provide information about the geology, stratigraphy, tectonics, magmatism, petrography, mineralogy, ore content, and metallogeny of the polymetallic deposits of Western Karamazar. In the Takeli and Kansai ore fields, despite the rather detailed geological study, little attention was paid to the mineral composition of the ores, especially the silver content. GENERAL CHARACTERISTICS OF THE STUDY Purpose of the study. The main goal of the dissertation work is a detailed study of the mineral composition of ores using the latest methods of analysis and the conditions for their formation in order to develop prospecting and evaluation criteria in the search for polymetallic mineralization. Research objectives. To achieve this goal, the following tasks were envisaged: a detailed study of the mineral composition of individual ore bodies and deposits of the Takeli and Kansai ore fields as a whole, especially silver mineralization, to identify the typomorphic features of individual minerals or mineral parag
