New data on the distribution of 329 lichen species in Oka Plateau (Eastern Sayan, Southern Siberia, Republic of Buryatia) are presented. 7 species are reported for the first time for lichen flora of Russia: Leptogium furfuraceum, Melanelixia villosella, Myxophora leptogiophila, Pachyphiale ophiospora, Physcia cf. integrata, Polycoccum clauzadei, Stigmidium psorae. 14 species are recorded for the first time to Southern Siberia: Arthonia clemens, Bacidina delicata, Caloplaca saxifragarum, Lecidea septentrionalis, Leciophysma finmarkicum, Leptogium intermedium, Phaeosporobolus alpinus, Rhizocarpon frigidum, Rinodina metaboliza, R. olivaceobrunnea, Tetramelas chloroleucus, T. phaeophysciae, Weddellomyces tartaricola, Xanthoria stiligera. The records of Myxophora leptogiophila, Pachyphiale ophiospora, Polycoccum clauzadei, Stigmidium psorae, Weddellomyces tartaricola are the first to Asia.

Gold Bearing

The Jinchang gold deposit is located in the eastern Yanji–Dongning Metallogenic Belt in Northeast China. The orebodies of the deposit are hosted within granite, diorite, and granodiorite, and are associated with gold-mineralized breccia pipes, disseminated gold in ores, and fault-controlled gold-bearing veins. Three paragenetic stages were identified: (1) early quartz–pyrite–arsenopyrite (stage 1); (2) quartz–pyrite–chalcopyrite (stage 2); and (3) late quartz–pyrite–galena–sphalerite (stage 3). Gold is hosted predominantly within pyrite. Pyrite separated from quartz–pyrite–arsenopyrite cement within the breccia-hosted ores (Py1) yield a Re–Os isochron age of 102.9 ± 2.7 Ma (MSWD = 0.17). Pyrite crystals from the quartz–pyrite–chalcopyrite veinlets (Py2) yield a Re–Os isochron age of 102.0 ± 3.4 Ma (MSWD = 0.2). Pyrite separated from quartz–pyrite–galena–sphalerite veins (Py3) yield a Re–Os isochron age of 100.9 ± 3.1 Ma (MSWD = 0.019). Re–Os isotopic analyses of the three types of auriferous pyrite suggest that gold mineralization in the Jinchang Deposit occurred at 105.6–97.8 Ma (includes uncertainty). The initial 187Os/188Os values of the pyrites range between 0.04 and 0.60, suggesting that Os in the pyrite crystals was derived from both crust and mantle sources.
