The carbon and oxygen isotopes of the quartz inclusions and hydrothermal carbonates in the gold deposits in the study area indicated that the source of carbon in the fluids of the main metallogenic stage was mainly the deep-seated magmatic source (Kong et al, 2015;Liu et al, 2016;Liu, Deng, et al, 2018;Shi et al, 2015;Xiong, 2017).…”

“…Samples of sulphide minerals from the Matouniu gold deposit yielded δ 34 S values ranging from À0.5 to 5.6‰, with an average value of 4.4‰; the limited range of δ 34 S values suggest relatively stable physicochemical conditions in the ore-forming fluids in this stage (Ma et al, 2018), which has features similar to those of typical magmatic-hydrothermal deposits (0 ± 5‰, Ohmoto, 1972;Ohmoto & Rye, 1997). Moreover, sulphide isotope compositions of the Matouniu gold deposit are consistent with those of other Yanshanian Au deposits in the Eastern Hebei region, such as the Xiajinbao (À0.2 to 3.7‰), Huajian (1.5-5.4‰), Jinchangyu (À4.4 to 5.2‰), Tangzhangzi (2.1-5.5‰), and Yuerya (À0.3 to 5.3‰) deposits; all of which are commonly thought to be of magmatic origin (He, 2015;Kong et al, 2015;Liu et al, 2016;Liu, Shao, et al, 2018;Shi et al, 2015;Shi et al, 2019;Song et al, 2016;Zhang, Shao, Wang, Liu, & Xiong, 2017;Zhang et al, 2020), indicating that the sulphur of the Matouniu gold deposit was derived from magmatic-hydrothermal sources.…”

The Matouniu gold polymetallic deposit in the Eastern Hebei Province (Jidong) in the northern margin of the North China Craton (NCC) is a skarn-type ore deposit. Geochemical data, zircon U-Pb, and Hf isotope analysis of the mineralization-related dioritic porphyrite and C-O-S-Pb isotopes from the deposit were used to investigate the origin, magmatic evolution, mineralization, and tectonic setting of the Matouniu gold polymetallic deposit. Zircon U-Pb dating reveals an emplacement age of 146.7 ± 1.1 Ma, indicating that the magmatism and mineralization occurred during the Late Jurassic. Geochemical, Hf, and Pb isotopic compositions indicate that the dioritic porphyrite was formed by the partial melting of the ancient mafic lower crust, leaving behind residual plagioclase, amphibole, and garnet, with traces of mantle material involvement. The S and Pb isotopic compositions revealed that both the ore-forming materials and the dioritic porphyrite were derived from a deep-seated magmatic source, which mainly originated from the lower crust, with minor input from the mantle. The C-O isotopic compositions suggest that the early ore-forming fluids had a mainly deep-seated magmatic source with minor meteoric water involvement, and were accompanied by continuous meteoric water involvement and water-rock interaction during the fluid migration. The Matouniu gold polymetallic deposit and Late Jurassic dioritic porphyrite associated with skarn mineralization formed under geodynamics involved a compressional regime that was associated with the continuous subduction of the Palaeo-Pacific Plate beneath the East Asia Plate.

“…These gold deposits are located in brittle‐ductile shear zones and fractures (Figure 2). Gold occurs as disseminated or quartz veins within either the Precambrian metamorphic basement (e.g., Songjianghe, Jiapigou, Paishanlou, Jinchanggouliang, and Jinchangyu; L. Liu et al., 2020; S. F. Liu et al., 2021; Song et al., 2016; X. H. Zhang et al., 2005; X. T. Zhang et al., 2019) or Mesozoic granites (e.g., Yu'erya; Kong et al., 2015). The sulfides in the ore include pyrite, chalcopyrite, galena, and sphalerite.…”

The northern margin of the North China Craton (NNCC) hosts Mesozoic gold deposits of significant economic importance. The metal sources of these gold systems have long been debated with mainly magmatic‐hydrothermal versus metamorphic fluid models. Mercury (Hg) isotopes, which undergo unique mass‐independent fractionation, can provide important insights into the source of metals in gold deposits due to the close association between Hg and Au in such systems. Here, we investigated the Hg isotopic composition of six gold deposits of the Middle Jurassic to Early Cretaceous age and potential source rocks in the NNCC. Variable ∆199Hg values were observed in bulk ore and pyrite samples (−0.28‰ to 0.34‰, n = 51) and coeval granites (−0.21‰ to 0.13‰; n = 25). The negative ∆199Hg values of bulk ore and pyrite samples mostly agree with that observed for metamorphic basement rocks (−0.37‰ to 0.11‰; n = 32). The positive ∆199Hg values of bulk ore and pyrite samples agree with those reported in marine sediments (0‰–0.3‰). So the data suggest binary mixing of ocean‐recycled Hg originated from the subducted oceanic slab, and terrestrial‐recycled Hg from the Precambrian basement in Mesozoic gold deposits. The contribution of Hg (and Au, by analogy) from both reservoirs varies depending on active continental arc versus intracontinental setting and is ultimately controlled by translithospheric heat flow driven by paleo‐Pacific plate subduction.

“…Recently, trace element analysis of ore minerals has been widely used in the study of the metal sources of gold deposits (Zhang et al ., 2014a; 2014b; Kong et al ., 2015; Mills et al ., 2015). For example, sedimentary pyrite generally has Co/Ni ratios of <1 (Bajwah et al ., 1987), while hydrothermal pyrite generally has Co/Ni ratios of >1 (Bralia et al ., 1979).…”

The metal source of gold deposits in the Jiaoxibei area, eastern China, has been investigated by many researchers, but no consensus has been reached so far. In this study, three typical gold deposits, the Xinli, Jiaojia, and Dayingezhuang deposits, were selected for trace element analysis of gold and pyrite to constrain the metal source. Pyrite from these three deposits has similar morphological and compositional characteristics, and can be divided into three types: Py1 with euhedral to subhedral textures, Py2 with subhedral to anhedral textures with micro‐fractures, and Py3 with subhedral to anhedral textures and intergrowing polymetallic sulfides. Among them, Py2 and Py3 were formed in the main ore‐forming stage and they are the dominant host minerals of visible gold. In these deposits, visible gold occurs mainly in micro‐fractures or as inclusions in Py2 and Py3. Most of the pyrite has extremely low concentration of invisible gold, indicating that visible gold in the Jiaoxibei district is not a product of the remobilization of invisible gold from earlier pyrite. Both Py2 and Py3 are characterized by low Co concentration of <100 ppm and Co/Ni ratio of <1, which are similar to those of pyrite in sedimentary rocks. Therefore, ore‐forming metals of these gold deposits in the Jiaoxibei district may originate mainly from a sediment‐related metal source.
