Dirin’
Sakha (Yakutia), Adycha-Taryn metallogenic zone, Russia
Orogenic goldAu
- Type
- Low-sulfide orogenic gold-quartz
Gold-quartz (gold-sulfide-quartz) occurrence of the Adycha-Taryn metallogenic zone, Yana-Kolyma gold belt: veins, vein zones and disseminations in Permian to Lower Jurassic sandstones and siltstones of the Kular-Nera slate belt, controlled by thrusts related to accretion of the Kolyma-Omolon microcontinent (mineralisation mostly at about 140-130 Ma). Gamyanin et al. (2018): milky quartz from +14.2 to +19.5 ‰ (calculated fluid +7.3 to +12.3 ‰ at 300 °C), ankerite from -9.1 to -6.1 ‰ in δ13C, sulfides from -6.6 to +5.4 ‰ in δ34S: increasing share of metamorphic fluids. Dirin'-Yuryakh in the text: lenticular quartz veins. Occurrence values: milky quartz +14.2 and +16.9 ‰; ankerite -6.1 ‰ in δ13C and +14.3 ‰ in δ18O. Coordinates not published (schematic map only).
