      <abstract xml:lang="ru">
        <p>В работе приводятся результаты датирования сульфидной минерализации Майского золоторудного месторождения с использованием Re-Os изотопной системы основных сульфидных минералов: арсенопирита, пирита и антимонита и изохронного метода оценки возраста. Сложное полистадийное образование изученных сульфидов, а также тесные взаимные срастания генетически различных минеральных фаз не позволили получить единую рений-осмиевую изохрону, соответствующую времени образования сульфидной минерализации. А мономинеральные изохроны по отдельным навескам каждого образца сульфидов оказались результатом смешения изотопно различных компонентов (радиогенного корового и нерадиогенного мантийного) и не имеют прямого геохронологического смысла. Геологически наиболее значимым результатом проведенного исследования следует рассматривать возрастную оценку 128,8±4,4 млн лет, полученную для сульфидной минерализации Майского месторождения с использованием рений-осмиевой систематики монофракций пирита и антимонита рудной стадии минерализации. Арсенопирит наиболее тесно ассоциирует с золотым оруденением, одна из разновидностей которого корродирует фромбоидальный пирит дорудной стадии, имеет максимальную долю корового компонента в изотопном составе осмия и образует линию смешения на изохронной диаграмме с кажущимся возрастом образования 458±18 млн лет. Начальный изотопный состав осмия изученных сульфидов указывает на смешанный, мантийно-коровый, источник вещества сульфидной минерализации. Вопрос о синхронности процессов рудогенеза и гранитоидного магматизма для района месторождения Майского остался неразрешенным (возраст гранитоидов по U-Pb системе циркона – 108 млн лет), тем не менее, возможным его решением стало бы дальнейшее определение изохронного Re-Os возраста по сульфидам рудного этапа из единого парагенезиса конкретного образца, содержащего как арсенопирит, так и пирит (+ антимонит) с золотом.</p>

        <p>The article presents the results of the sulfide mineralization dating of the Mayskoe gold ore deposit using the Re-Os isotope system and isochron age estimation method of the main sulfide minerals: arsenopyrite, pyrite, and antimonite. The complex multistage formation of the studied sulfides, as well as the close intergrowths of genetically different mineral phases, did not allow obtaining a single rhenium-osmium isochron corresponding to the formation time of sulfide mineralization. Isochrones for single minerals, collected from each sulfide sample, turned out to be the result of isotopically distinct components mixture (radiogenic crustal and non-radiogenic mantle) and do not make sense from the geochronological point of view. In terms of geology, the most significant result of the study is an age estimation of 128.8 ± 4.4 Ma, obtained for the sulfide mineralization of Mayskoe deposit using Re-Os isotope dating of single fractions of pyrite and antimonite of the ore mineralization stage. While arsenopyrite is most closely associated with gold mineralization, one of the arsenopyrite varieties corrodes framboidal pyrite of the pre-ore stage, has a maximum of the crust component in the osmium isotopic composition and forms a mixing line in the isochron diagram with an apparent formation age of 458 ± 18 Ma. The initial osmium isotopic composition of the studied sulfides indicates a mixed mantle-crust source of sulfide mineralization. The issue of simultaneous ore genesis and granitoid magmatism in the Mayskoe deposit remained unresolved (the age of granitoids according to the U-Pb zircon system is 108 Ma). However, a possible solution could be the further determination of the Re-Os isochron age of the ore mineralization sulphides from the single paragenesis of a specific sample containing both arsenopyrite and pyrite (+ antimonite) with gold.</p>
