“…Thermotectonic modeling shows that a c. 6 km cover was removed since the gold mineralizing event in the Mu‐Ru district (Figure 11). Exhumation magnitude estimates from gold deposits in the Jiaobei Uplift suggest that the deposits have also been unroofed from depths of 6 ± 2 km (Liu et al., 2010; Liu, Fan, et al., 2017; Zhang, Groves, et al., 2020). As a result, a similar degree of exhumation on both sides of the gold province rules out the possibility that differential degrees of post‐mineralization erosion resulted in the heterogeneous gold endowment in the Jiaodong gold province.…”

“…(2021) highlight the importance of basement structural inheritance in controlling the localization of gold mineralization because such basement faults may link favorable deposit traps with deeper‐seated fluid pathways. In addition, differential erosion at the regional scale induces heterogeneous gold endowment (Gong et al., 2021; Sillitoe et al., 2019; Yu et al., 2022; Zhang, Groves, et al., 2020). Moreover, given that the gold deposits were formed during exhumation of metamorphic core complexes caused by the NW‐SE extension, differential exhumation degree could potentially result in differential fluid migration and metal precipitation.…”

“…At the deposit scale, greater complexity of structural features can lead to the heterogeneous gold endowment through enhanced focusing of gold‐bearing hydrothermal fluid (Groves et al., 2018). For example, the difference in the plunge of ore‐controlling faults is often a critical factor in the formation of high‐grade ore zones (Zhang, Groves, et al., 2020). At the regional scale, Wiemer et al.…”

Low‐Temperature Thermochronology for Defining the Tectonic Controls on Heterogeneous Gold Endowment Across the Jiaodong Peninsula, Eastern China

et al. 2023

This study presents a low-temperature thermochronological data set from the Jiaodong Peninsula in eastern China, including new zircon U-Th/He and apatite fission-track data from the Sulu Terrane in the eastern side of the Jiaodong Peninsula and published data from the Jiaobei Uplift to the west. These data reveal differential tectonic evolution between the Jiaobei Uplift and the Sulu Terrane, which is responsible for their heterogeneous gold endowment. Thermal history inverse modeling and structural analysis indicate three broad periods of cooling in the Sulu Terrane. These include: (a) slow cooling from 114 to 50 Ma; (b) rapid cooling from 50 to 40 Ma; and (c) tectonic stability after 40 Ma with little cooling. This thermotectonic evolution pattern shows that the local tectonic evolution of Sulu Terrane and Jiaobei Uplift are relatively independent, although they share identical far-field geodynamic controls. The critical characteristic is the Early Cretaceous extension within the Sulu Terrane was much weaker than that in the Jiaobei Uplift that underwent a rapid period of uplift in the Aptian. The differential tectonic evolution of the two areas induced variation in structural architecture and consequential differences in degree of extension that are important factors in defining the heterogeneous gold endowment rather than simply suggested differences in ore-forming fluid chemistry, metal precipitation mechanism, and/or exhumation levels. The intense extension in the Jiaobei Uplift was conducive to voluminous fluid migration and gold precipitation. In contrast, the much weaker extensional setting in the Sulu Terrane was not conducive to large-scale fluid migration from deep. Plain Language SummaryThe Izanagi Plate was subducted westward underneath the Eurasian continent beginning in the Jurassic, influencing the tectonic evolution and forming a remarkable metal endowment in eastern China. The Jiaodong gold province in China is composed of the Jiaobei Uplift to the west and Sulu Terrane to the east, hosting gold resources of >5,000 tonnes. More than 85% of the gold resources are hosted in orogenic gold deposits in the Jiaobei Uplift, whereas gold endowment is more limited in the Sulu Terrane. Structural analysis and low-temperature thermochronology from our new study reveal that the tectonic evolution of the Sulu Terrane is different from that previously described for the Jiaobei Uplift. Differential tectonic evolution shows that the local ore-controlling structural evolution of the two areas is relatively independent although both are controlled by the subduction of the Izanagi Plate. This independence reflecting differences in degrees of extension appears to be the major factor responsible for the heterogeneous gold endowment in the Jiaodong gold province. The greater amount of extension in the Jiaobei Uplift relative to that in the Sulu Terrane was more conducive to large-scale fluid migration in the Early Cretaceous, which led to the world-class gold deposit formation.

“…The majority of Jiaodong type gold deposit, are characterized by massive gold ore bodies in deep-seated faults, such as Jiaodong Sanshandao gold deposit occurring in Sansandao fault, Liaodong Wulong gold deposit occurring in Jixingou fault, and Jilin Jiapigou gold deposit occurring in Jiapigou fault (Zhang et al, 2019;Zhang et al, 2020;Han et al, 2021).…”

“…The proved gold reserves are only 340 t in the early stage of prospecting. As a result of the discovery of Jiaojia type gold deposit, geologists recognized that the regional faults not only created channels for transmitting ore, but also favored the occurrence space for mineralization (Groves et al, 2005(Groves et al, , 2020Zhang et al, 2020). Therefore, based on above metallogenic theory and geological practice, a host of large gold deposits (such as Sanshandao, Hexi, Fayunkuang) were successively discovered in the deep-seated structures (Li et al, 2013;Guo et al, 2017).…”

Crustal response induced by the subduction of Paleo-Pacific Plate, is crucial to study the metallogenic law and prediction of Jiaodong type gold deposit. Gold deposits are preferentially hosted in the lithospheric-scale second-order faults, which provide migration channels, mineralization corridors, and the physicochemical conditions. Super-large gold deposits in northwestern Jiaobei Terrane are generally controlled by regional linear faults, such as Sansandao, Jiaojia, Zhaoping and Qixia faults. However, Zhaoping fault is exposed sporadically (in Xiadian and Jiangjiayao gold deposits) beneath a thick cover of Quaternary basalts, which indicating that limited information can be obtained by traditional geological survey. In this study, high-precision geophysical surveys such as gravity and controlled source audio frequency magnetotellurics (CSAMT) are conducted in the Shanhou gold deposit, which hosted in southern part of Zhaoping fault. Three integrated geophysical profiles results further identified the spatial distribution of second-order oblique-slip faults of Zhaoping fault and established the relationships between brittle deformation and mineralization. The spatial variability of stratum (high density 2.82 g/cm3 and intermediate to high specific resistivity 4000 Ω m), brittle-slip faults (intermediate density 2.73 g/cm3 and low specific resistivity 200 Ω m) and magmatite (low density 2.57 g/cm3 high specific resistivity 8000 Ω m) are identified by two inversion techniques, including the man-machine interactive inversion technology and nonlinear conjugate gradient technology. In addition, the geophysical inversion pseudo sections delicately portray a smooth-out waveform low specific resistivity anomaly, which strongly couples with the spatial ore-hosted locations and enrichment places. The gold mineralized alteration zones generally dips to southeast and the angle changing from 45° to 30°, which are strong coupling with the large-scale acid magmatic intrusion and extensional tectonics occurred in the late Mesozoic. Finally, according to the deep prospecting prediction, a gold ore body with 10 m in thickness was revealed by drilling below the depth of 1,015 m, which is hosting in the brittle deformation of Zhaoping fracture zone.
