В статье приводятся результаты геологического, минералогического, геохимического и изотопногеохимического изучения гранитоидов (чарнокитов) татарниковского комплекса, расположенного в северной части Байкальского краевого выступа фундамента Сибирского кратона. Гранитоиды имеют возраст 1.85 млрд лет и подобно другим неметаморфизованным гранитоидам и ассоциирующим с ними вулканитам с возрастом 1.88–1.84 млрд лет, широко распространенным в пределах южной части Сибирского кратона, входят в структуру Южно-Сибирского постколлизионного магматического пояса. Гранитоиды татарниковского комплекса образуют серию небольших массивов, приуроченных к Даванской зоне смятия. Однако, в отличие от пород Даванской зоны, гранитоиды не подвержены процессам динамометаморфизма, милонитизации и метасоматоза, что указывает на их формирование после становления структуры этой зоны. Образование гранитоидов совпадает по времени с формированием наиболее молодых образований Северо-Байкальского вулканоплутонического пояса (1.85–1.84 млрд лет). Среди гранитоидов татарниковского комплекса выделяются две фациальные разновидности с постепенными переходами: крупнозернистые породы и средне- и мелкозернистые порфировые породы. Минеральный состав гранитоидов, а именно присутствие в них ромбического пироксена, позволяет относить их к чарнокитам. Результаты, представленные в статье, основываются на изучении чарнокитов в самом крупном из массивов татарниковского комплекса – Татарниковском массиве. Крупнозернистые гранитоиды Татарниковского массива по своему химическому составу соответствуют монцонитам и сиенитам, а мелкозернистые порфировые гранитоиды – граносиенитам. Все гранитоиды по составу близки щелочным и известково-щелочным, умеренно-глиноземистым (ASI=0.83–0.97), железистым (FeO*/(FeO*+MgO)= =0.86–0.89) гранитам. Исследованные породы характеризуются высокими концентрациями Nb, Y, Zr, Ba и пониженными содержаниями Sr. По своим геохимическим характеристикам породы соответствуют гранитам А-типа. Проанализированные гранитоиды Татарниковского массива характеризуются отрицательными величинами εNd(t)=–1.4…–3.5 и модельным возрастом ТNdDM=2.4–2.5 млрд лет. Оценка температур начальных стадий кристаллизации гранитоидных расплавов показала, что формирование гранитоидов происходило при высоких температурах – 890–960 °С (температура насыщения расплава цирконом). Кристаллизация гранитоидных расплавов осуществлялась в гипабиссальных условиях при давлении 2.2–2.9 кбар, а также в условиях низкой или умеренной фугитивности кислорода. Минералогические, геохимические и изотопно-геохимические данные свидетельствуют о том, что чарнокиты татарниковского комплекса могли быть образованы за счет плавления мафических пород нижней коры (габброидов, ферродиоритов), которые были сформированы в результате дифференциации мантийных толеитовых магм, внедрившихся в основание континентальной коры. Высокие концентрации Ba и положительные Eu аномалии на спектрах распределения редкоземельных элементов (РЗЭ) крупнозернистых гранитоидов позволяют допускать, что гранитоиды формировались посредством частичного плавления корового мафического источника. Мелкозернистые порфировые гранитоиды, обнаруживающие более высокие содержания кремнезема и более низкие содержания Ва, Zr по сравнению с крупнозернистыми разностями, а также отрицательные Eu аномалии на спектрах распределения РЗЭ, были образованы в результате фракционной кристаллизации гранитоидного расплава. В масштабе становления единой структуры Сибирского кратона геодинамическая обстановка формирования чарнокитов татарниковского комплекса рассматривается как постколлизионное растяжение на основании их принадлежности к Южно-Сибирскому постколлизионному магматическому поясу. Однако в более локальном масштабе Байкальского выступа фундамента кратона внедрение гранитоидов татарниковского комплекса, так же как пород СевероБайкальского вулканоплутонического пояса, гранитоидов приморского и абчадского комплексов, пересекающих породы Акитканского складчатого пояса, коллизионные события в котором завершились на временном рубеже 1.98–1.97 млрд лет, происходило в обстановке внутриконтинентального рифтогенеза.

The article reports on the geological, mineralogical, geochemical and isotope-geochemical studies of granitoids (charnockites) from the Tatarnikovsky massif located in the northern part of the Baikal uplift of the Siberian craton basement. The age of the studied granitoids is 1.85 Ga. Like other unmetamorphosed granitoids and associated volcanic, the granitoids dated 1.88–1.84 Ga are abundant in the southern area of the Siberian craton. These rocks are a part of the South Siberian post-collisional magmatic belt. The Tatarnikovsky granitoids form a series of small massifs confined to the Davan tectonic zone. However, unlike the rocks of the Davan zone, these granitoids have not been subjected to dynamometamorphism, mylonitization and metasomatism, and seem younger than the geologic structure of this zone. The formation of granitoids coincides in time with the youngest formations in the North Baikal volcanoplutonic belt (1.85–1.84 Ga). The Tatarnikovsky granitoids have two facies varieties – coarse-grained and medium-fine-grained porphyric, the transition being gradual. Considering the mineral composition of the granitoids, specifically the presence of orthopyroxene, these rocks can be classified as charnockites. The research results presented in this article are based on the study of charnockites in the Tatarnikovsky massif, the largest in the Tatarnikovsky complex. The chemical composition of the Tatarnikovsky coarse-grained granitoids corresponds to monzonite and syenite, and fine-grained porphyry granitoids are granosyenite. All the studied granitoids are close to alkaline and calc-alkaline, metaluminous (ASI=0.83–0.97), ferrous (FeO*/(FeO*+MgO)=0.86–0.89) granite, with high concentrations of Nb, Y, Zr, and Ba, and low concentrations of Sr. According to their geochemical characteristics, the Tatarnikovsky granitoids correspond to A-type granite. These rocks show negative values εNd(t)=–1.4…–3.5 and model age ТNdDM=2.4–2.5 Ga. The temperature estimated for the initial stages of crystallization of granitoid melts suggests that granitoids formed at high temperatures, 890–960°С (i.e. the zircon saturation temperature). The granitoid melts crystallized in hypabyssal conditions at the pressure of 2.2–2.9 kbar, as well as in conditions of low or moderate oxygen fugacity. According to the mineralogical, geochemical and isotope-geochemical data, the Tatarnikovsky charnockite could have resulted from melting of mafic rocks from the lower crust (gabbroid, and ferrodiorite) which are products of differentiation of the tholeiitic mantle magmas that had intruded into the base of the continental crust. Taking into account the high concentrations of Ba and the positive anomalies of Eu in the distribution spectra of rare-earth elements (REE) of the coarse-grained granitoids, it can be suggested that these granitoids are the products of partial melting of the crustalmafic source. The fine-grained porphyry granitoids with higher silica contents and lower Ba and Zr contents than those in the coarse-grained granitoids, as well as the negative anomalies of Eu in the REE distribution spectra, are the products of fractional crystallization of the granitoid melt. With regard to formation of the unified structure of the Siberian craton, the geodynamic setting for formation of the Tatarnikovsky charnockite is considered as postcollisional extension due to the fact that these rocks belong to the South Siberian post-collisional magmatic belt. However, on a more local scale of the Baikal uplift of the Siberian craton basement, we suggest that the intercontinental rifting setting was in place during the intrusion of the Tatarnikovsky granitoids, the rocks of the North Baikal volcanoplutonic belt, the granitoids of the Primorsky and Achadsky complexes that cross the rocks of the Akitkan fold belt, collision events in which ceased 1.98–1.97 Ga ago.
