“…Moreover, their predecessors obtained sericite Rb‐Sr isochron ages from 110‐Ma granite porphyry and 200‐Ma granodiorite, which are 107 ± 5 Ma and 110 ± 4 Ma, respectively. The ages of ~110 Ma can be considered to be the timing of gold mineralization, which is similar to those obtained from the other gold deposits in NE China (Qi et al, ; Ren et al, ), continental margin of NE China (Han et al, ) and Northern Lesser Xing'an Range (Han, ) and Russian Far East (Goryachev & Pirajno, ).…”

The Jinchang Au deposit is a large‐sized deposit in Heilongjiang Province, and mineralization is closely related to the Early Cretaceous granitoids. The orebodies occurred within granite, granite porphyry, granodiorite, and diorite. Gold mineralization type consists of crypto‐explosive breccia, vein, and veinlet‐disseminated types. In this paper, we present U–Pb age as well as major and trace element geochemistry of intrusive bodies from the Jinchang deposit. Our study indicates that granite, granite porphyry, and granodiorite from the Jinchang deposit are calc‐alkaline to high‐K calc‐alkaline with geochemical characteristics of typical island‐arc environment. Diorite and diorite porphyrite show calc‐alkaline affinities with geochemical characteristics of adakite or adakitic rock. Concordant zircon U–Pb ages of 184.69 ± 0.98 Ma and 203.62 ± 0.86 Ma are obtained from granites; 190.4 ± 4.7 Ma, 205.88 ± 0.95 Ma, and 109.0 ± 2.4 Ma are obtained from granite porphyry, granodiorite, and quartz diorite. Combined with previous geochronological data, the diagenetic ages for granitoids in the Jinchang deposit are mainly focused on 2 episodes: 110 ~ 120 Ma and 185 ~ 200 Ma. The corresponding tectonic settings for the 2 episodes of magmatic activities are subduction of the Izanagi Plate towards the Eurasian Plate, and post‐collision system after the collision of North China Craton and Jiamusi‐Khanka Massif, respectively. We suggest that the magmatism (110 ~ 120 Ma) formed adakitic diorite and diorite porphyrite and closely associated with mineralization. Upwelling mantle results in partial melting of the lower crust and extract and transfer metals to the upper crust for further concentration. It also reveals that Jinchang Au deposit is an adakite‐associated deposit.

“…These data lead us to argue that the epithermal gold deposits in the Lesser Xing'an Range and Zhangguangcai Range formed mainly between 124 and 107 Ma (Table 1; Figure 11). The mineralization ages of the epithermal gold deposits in the Zhangguangcai Range are also similar to the porphyry or porphyry-hydrothermal vein Cu-Au deposit at Xiaoxinancha and Nongping in the Zhangguangcai Range (Han, Sun, Bai, et al, 2013;Ouyang et al, 2013;Ren et al, 2015;Shu et al, 2016;Wang et al, 2010;Zeng, Guo, Zhou, & Duan, 2016) which Xiaoxinancha Cu-Au deposit has Molybdenite Re-Os age of (Ren, Wang, Qu, Zhao, & Chu, 2011 (Figure 12a).

The newly discovered Yongxin Au deposit in the Lesser Xing'an Range of north‐eastern Heilongjiang Province, NE China, has a resource of ~20 t with a grade of 4.1 g/t Au. The deposit is hosted by Carboniferous syenogranite and mylonite, and Cretaceous diorite porphyry and granite porphyry. The syenogranite has a LA‐ICP‐MS 206Pb/238U zircon age of 316 ± 2 Ma, and both the granite porphyry and diorite porphyry yield an age of 119 ± 1 Ma. The Rb–Sr isochron age of Au‐bearing pyrite from hydrothermal breccia‐type ore is 107 ± 4 Ma, and this is interpreted as the mineralization age of the Yongxin deposit. In combination with published geochronological data, we argue that epithermal Au mineralization in NE China formed during the period ca. 124 to 107 Ma and was produced during rollback of Palaeo‐Pacific oceanic slab. The Cretaceous epithermal Au deposits are distributed in the Erguna Massif, Lesser Xing'an Range, Zhangguangcai Range, and Jiamusi and Nadanhada terranes. In combination with the coeval porphyry Mo deposits present in these areas, we propose that the Erguna Massif, Lesser Xing'an Range, north‐eastern Great Xing'an Range, and eastern Jiamusi and Nadanhada terranes, where only epithermal gold deposits were discovered up to date, might be prospective for concealed porphyry Cu or Mo deposits.

The Jinchang gold deposit has been extensively studied, but precise dates for its formation are debated. Native gold mainly occurs as inclusions within pyrite and quartz. In this study, we analysed quartz crystals coeval with gold precipitation from two different types of mineralization using the ArgusVI multi-collector noble gas mass spectrometer by the stepwise crushing technique to resolve the timing and genesis of gold mineralization. 40Ar/39Ar dating of quartz samples (J12Q) from breccia ore yields a plateau age of 109.87 ± 0.86 Ma, and an inverse isochron age of 109.87 ± 0.88 Ma. Quartz samples (J18Q) from vein ore yields a slightly younger plateau age of 107.76 ± 0.85 Ma, with an inverse isochron age of 107.76 ± 0.92 Ma. These dates place the ore-forming age of the Jinchang gold deposit at 107~110 Ma, much younger than previously published radiometric ages, suggesting the gold mineralization is spatio-temporally associated with the granite porphyry. The formation of the Jinchang gold deposit is consistent with the regional late Mesozoic porphyry-epithermal gold mineralization event in the Yanbian-Dongning area. Finally, our study shows that 40Ar/39Ar of quartz can be used as a powerful tool to date the formation ages of hydrothermal ore deposits.
