Te-Bi melts have been recognized as crucial agents for scavenging gold in gold deposits related to magmatism, often characterized by a notable Au-Te-Bi association. This association is also recognized in gold deposits of the Jiaodong district, though the specific roles of Te and Bi in gold enrichment here have not been thoroughly evaluated until no...
The role of bismuth melts in scavenging Au from hydrothermal fluids has been increasingly recognized in the last decade, but the question of how the Au extracted by such melts transforms into nuggets to form high-grade ores remains obscure. Here, we have characterized the nanostructure of gold nanoparticles (AuNPs) in Bi-rich gold ores that precipi...
Mantle properties and metasomatic processes, together with interlayer interactions, in orogenic belts are still under debate. Post-collisional magmatic rocks could provide secondhand constraints on these issues. We have conducted an integrated geochronological, geochemical and isotopic study on post-collisional Zhanwa dolerites, the Dashui granodio...
Studies have revealed the key role of deep-seated, ore-forming fluids and metals in the generation of the Early Cretaceous large-scale gold deposits in the Jiaodong gold province of eastern China. However, how the ore-forming materials were transported to shallow crustal levels remains unclear. Here, we investigate trace elements and sulfur isotope...
Critical Metals Ga, Ge and In in the Global Pb-Zn Deposits: Current Understanding, Challenges and Perspectives
Gold deposits in Precambrian cratons were mostly generated during the formation and stabilization of the cratons, but the North China craton is unusual in that its gold deposits were mainly formed ∼1.7 b.y. after its stabilization. A magmatic-hydrothermal origin or mantle-derived fluid source has been proposed for the giant gold deposits of the Jia...
Due to the combined influences such as ore-forming temperature, fluid and metal sources, sphalerite tends to incorporate diverse contents of trace elements during the formation of different types of Lead-zinc (Pb-Zn) deposits. Therefore, trace elements in sphalerite have long been utilized to distinguish Pb-Zn deposit types. However, previous discr...
Multi-period mineralizations commonly form superimposed deposits in the orogenic belt, resulting in some disputes about the ore geneses and metallogenic background. Here, we present a comprehensive geological and geochronological study on the Yindongpo super-large gold deposit in the Tongbai composite orogen, central China, to reveal the ages of mu...
The Qingchengzi gold ore-concentration district, in the Liaodong Peninsula, northeastern North China Craton, is dominated by altered rock-type gold deposits and hosted within metamorphic rocks of the Paleoproterozoic Liaohe Group. The deposits are mainly controlled by a low-angle, north-dipping thrust structural system, containing numerous carbonac...
The North China Craton is well endowed with numerous Early Cretaceous gold deposits that are mainly hosted in Archean to early Paleoproterozoic metamorphic rocks and late Mesozoic granitoid intrusions intruding the former. Whether or not gold was sourced from those metamorphic rocks remains hotly debated. Here we present trace element and S-Pb isot...
Titanite is a common accessory mineral in igneous rocks and hydrothermal deposits. Micro-texture and in situ chemical analyses on titanite are expected to reveal complex magmatic-hydrothermal processes. The Liangwan granitic pluton in the Tongbai Orogen is dominated by monzogranite with abundant mafic microgranular enclaves (MMEs). In this paper, a...
Significance
There is a common consensus that lode gold deposits mostly precipitated from metamorphic fluids via fluid boiling and/or fluid–rock interaction, but whether magmatic hydrothermal fluids and the mixing of such fluids with an external component have played a vital role in the formation of lode gold deposits remains elusive. We use garnet...
The North China craton was stabilized in the late Paleoproterozoic but experienced significant removal of ancient lithospheric keel in the late Mesozoic that resulted in the formation of numerous world-class gold deposits with combined reserves of more than 7000 t of gold. However, it remains uncertain whether the North China craton contains older...
The northwestern part of the Jiaodong Peninsular is the most important gold producer in China. Recently, the discovery of gold mineralization at a depth of 3,000 m below the surface in the region has generated a great interest for profound prospecting potential among the explorers. However, the maximum exploration depth and the potential of differe...
Early Cretaceous granitic plutons in the Jiaobei Terrane, Eastern China, contain abundant mafic enclaves (MMEs), which are important to understand the tectonic settings and genesis of gold mineralization in the Jiaodong Peninsula. Here, we combine petrology, geochronology, and isotopic geochemistry for MMEs and host granitoids to constrain their te...
The Xiaoqinling district, situated at the southern North China Craton, is the second largest gold province in China. The genesis of gold deposits in this district, however, has been debated for decades because of lacking unequivocal constraints on mineralization age and gold source(s). In this study, we present ore-related hydrothermal rutile U-Pb...
Mafic microgranular enclaves (MMEs) are hosted by the Early Cretaceous granitic plutons from the Jiaodong Peninsula and are crucial for constraining the petrogenesis of these plutons and understanding the lithospheric evolution in the eastern North China Craton (NCC). This paper presents new geochronological, bulk-rock geochemistry, and Sr-Nd-Hf is...
The Dayingezhuang Au deposit in the Jiaodong district, eastern margin of the North China Craton is hosted in Mesozoic granitic rocks and consists of quartz-sulfide veins/veinlets and sulfide disseminations in alteration envelopes. Previous studies mainly focused on the geochronology, sources of ore-forming fluids and metals to investigate the ore g...
The Fudian ore field in the southern North China Craton hosts the giant Donggou porphyry Mo deposit and several Pb-Zn-Ag vein deposits. Ore genesis of the Pb-Zn-Ag deposits and their relationships with the Donggou porphyry-related system are still controversial, which further restricts the regional prospecting and exploration. The Laodaizhanggou Pb...
The Hongtuling Au-Mo deposit on the southern margin of the North China Craton consists of Au veins and minor Mo veins that formed at ∼130 Ma and ∼204 Ma, respectively. Mo mineralization is dominated by molybdenite that is associated with K-feldspar, quartz and calcite, whereas Au mineralization occurs mostly as auriferous quartz-sulfides veins asso...
The West Qinling orogen, central China is endowed with dozens of world-class sediment-hosted gold deposits, most of which have formed from metamorphic fluids released from Paleozoic sedimentary rocks during the Triassic collisional orogeny. Here we present trace element and sulfur isotope data of gold-bearing pyrite and arsenopyrite, along with oxy...
The newly discovered Laoliwan large Ag-Pb-Zn deposit is located in the Xiaoshan district, southern margin of North China Craton, which is different from other types of Ag-Pb-Zn deposit in the area since the ore bodies are mainly hosted in the Laoliwan granite porphyry and controlled by the regional faults. The mineralization could be subdivided int...
The Daqiao gold deposit is hosted in organic-rich Triassic pumpellyite-actinolite facies metamorphosed turbidites in the West Qinling orogen, central China. Gold mineralization is characterized by high-grade hydraulic breccias (B and C ores) that overprint an earlier tectonic breccia (A ore). A complex paragenesis is defined by four sulfide stages:...
The southern North China craton hosts numerous world-class porphyry Mo and Pb-Zn-Ag vein deposits. Whether or not the Pb-Zn-Ag veins are genetically associated with the porphyry Mo system remains contentious. Here we focus on the genetic relationships between the Sanyuangou Pb-Zn-Ag vein deposit and the world-class Donggou porphyry Mo deposit, and...
