Granitoid magmatism in the Arminskii block of Central Sikhote Alin (Primorye, Far Eastern Russia): U–Pb geochronology, 3He/4He isotopy, petrochemistry, and ore mineralization

Research reveals distinct structural and temporal patterns in granitoid magmatism within the Arminskii block of Central Sikhote Alin, linking specific rock series to unique ore mineralization types. The Tatibi gabbromonzodiorite series is associated with gold-ore occurrences, including the potential Glukhoe deposit, while the Olgino leucocratic granite series correlates with known tin-sulfide ore deposits. Using U–Pb geochronology and ³He/⁴He isotopy, the study determines the conditions for rock generation and provides precise timing for mineralization events, offering new insights into the region's geological history and resource potential.
