ISSN: 2776-0979, Volume 3, Issue 4, April., 2022 167 The maximum amount of gold was detected in spessartites (115 mg/t). In addition, its content decreases as follows: diorite porphyrites (87 mg/t) - vogezites (32 mg/t) - kamptonites (29 mg/t) - kerasantites (27 mg/t). In the eastern part of the Chakilkalyan-Qoratepa mining region, the open accumulation of sheelite in spessartites, monchikites, vogezites and camptonites involved in the analysis of alkaline basaltoids-lamprophyre formation rocks and the formation of mantle magmatism in indicates a potential mineralization of gold and tungsten [8, 9]. At the boundary of the Yachton field, the rocks of the alkaline basaltoid-lamprophyre formation are spatially combined with the gold and tungsten ores of the lower stratum of the Yachton deposit, localized in the porphyry mesotropic biotite-amphiboles of the main intrusive phase of the yachton complex and leukocratic amphibole-biotite granodiorites. The mineralization of the lower tier of the Yahton deposit is bimetallic in nature with the spatial separation of tungsten ore and gold ore bodies and with telescoping elements of different types of mining in separate parts of the ore zone. The high content of gold is accompanied by high amounts of As, Ag, Te, Se and Bi, indicating that its pyrite-arsenopyrite, tetradimite-tellurovismutite, gold-hessite and gold-silver paragenetic mineral associations are related. ISSN: 2776-0979, Volume 3, Issue 4, April., 2022 168 The ore bodies and mineralized zones of the lower tier of the Yahton deposit are accompanied by endogenous sets of typomorphic elements for the geochemical association deposit, which includes W and Au and Bi, Te, As, Ag, Se, Mo, Cu, Sb, Zn, Pb. In the combined carbonyl migration of gold and tungsten from deep-seated sources, possibly lies the reasons for the paragenesis of natural gold and sheelite in the lower tier deposits of the Yahton deposit. The plateau phase of the geodynamic evolution of the Chakilkalyan mountains is characterized by the formation of two main focal structures (Yachton and Sukar) covering the upper mantle, with a deep level of magma generation. For deep-bed furnace structures, such structures are characterized by geochemical specialization in gold mining with postcollision granitoids and indicator elements (Bi, Ag, As, Se, Te and Sb) and rare metal mineralization with satellites Re and Hf (W, Mo), is characterized by the spatial location of the most artificial products of alkaline- basaltoid magmatism. This geochemical specialization significantly determines the gold-rare metal metallogenic profile of the region. The yacht area is a sign of potential mineralization of alkaline basaltoids and lamprophyre formation rocks and a comparison of spatially located gold-tungsten mineralization with them (see Table 1) once again emphasizes that some geochemical properties of alkaline basaltoids and lamprophyre formation rocks are inherited by ore. Most of these rocks are rock-forming from geochemically specialized elements (Au, Ag, As, W, Bi, Te, Se, Sb) and are part of a typomorphic productive association of apogranitoid gold-tungsten mining. All of the above are alkaline-basaltoid dyes and blast tubes, and the gold-tungsten mineralization complex combined with them in time and space has a paragenetic correlation. The formation of alkaline basaltoids-lamprophyres is the result of the formation of rocks and processes at the depth of artificial ore, and in its formation uses a single system of faults as a way to enter the upper horizons of the earth's crust.
