“…The relationship between magma and gold and silver mineralization in the Weishancheng ore concentration area has been a subject of considerable controversy in previous studies. The U-Pb geochronological results reveal that the intrusion ages of the two plutons are relatively close to the gold and silver metallogenic age (Chai, 2021;Chai et al, 2024;Gu, 2017;Li et al, 2023;Wang, 2014;Wang et al, 2016Wang et al, , 2017Zhang, 2021). S-Pb-H-O isotopes indicate that the magmatic intrusion exhibits a certain genesis relationship with gold and silver mineralization in this area, providing lead sources and mineralization materials for the mineralized zone (Chai, 2021;Chai et al, 2024;Li et al, 2009).…”

“…This suggests that there is no significant homologous relationship between the two (Jin, 2021;Li et al, 2009). The mineralization age of the gold and silver deposits in the Weishancheng ore concentration area can be roughly divided into two periods: the Early Cretaceous (119-130 Ma) and the Carboniferous Devonian (301-409 Ma) (Chai, 2021;Jiang, Nie, Fang, Liu, Zhang, et al, 2009;Li et al, 2023;Zhang et al, 2008Zhang et al, , 2013, which significantly postdate the intrusion age of the Taoyuan pluton. Therefore, the Taoyuan pluton cannot be considered as a source of energy or hydrothermal solution for gold and silver mineralization.…”

The Weishancheng area of Tongbai County, Henan Province, is an important Au‐Ag polymetallic ore concentration area in China, characterized by a widespread distribution of plutons and frequent magmatic activities. To investigate the genetic relationship between magmatism and the mineralization of gold and silver polymetallic deposits in the area, this study focuses on the porphyritic monzogranite of the Liangwan pluton and the biotite granite of the Taoyuan pluton in detail. The zircon U‐Pb age of the Liangwan pluton is 128.5 ± 0.7 Ma, placing its intrusion age in the Early Cretaceous. Similarly, the zircon U‐Pb age of the Taoyuan pluton is 431.3 ± 2.7 Ma, indicating an intrusion age in the Early Silurian. Petrogeochemical analysis reveals that both the Liangwan and Taoyuan plutons exhibit high SiO2, Na2O and Al2O3 contents, along with low MgO, Fe2O3 and CaO contents, indicating a (high‐K) calc‐alkaline series, and have the properties of peraluminous I‐type granite. The total rare earth elements (REE) concentrations are low, with noticeable fractionation between light and heavy REE, and a negative Eu anomaly. High‐field‐strength elements (such as Nb, Ta, P, Ti) are depleted, while the large‐ion lithophile elements (such as Rb, K, Pb) are enriched. The εHf(t) values of the Liangwan and Taoyuan plutons range from −16.1 to −18.8 and from 11.0 to 14.6, respectively. The mean values of Hf two‐stage model ages (TDM2) are 603 Ma and 2230 Ma, respectively. These results suggest that the Liangwan pluton may have formed through partial melting of ancient crustal materials in the Palaeoproterozoic, during extensional tectonic events following the subduction of Izanagi Plate. It appears closely linked to Au‐Ag mineralization in the ore concentration area. The Taoyuan pluton likely originated from the depleted mantle and experienced some degree of crustal contamination. However, it is unrelated to regional mineralization.

“…For example, in the case of a vertical metal hydrothermal mineralization system, the altered mineralization zones situated in the upper portion of the sediment are prone to weathering and denudation, while the ore sources located in the lower sections of the sediments are more likely to be safeguarded (Zhai, 1999). In order to evaluate the rate of sediment denudation, identify undiscovered ore deposits, investigate geochemical peculiarities, and facilitate mineral exploration, quantitative assessments of ore denudation depth are commonly employed (Li et al, 2006;Liu and Ma, 2007).…”

Dorzecze Song Hien Rift, położone w północno-wschodnim Wietnamie, zostało uznane za ważny region występowania złóż złota, w tym m.in Złoże Pac Lang. Do opisania charakterystyki geologicznej tego złoża zastosowano kilka metod, takich jak obserwacje petrograficzne, analizy elementarne i elementy geochemiczne oraz modele podziału pionowego pierwotnego halo. Badania obejmowały zdarzenia geologiczne, które miały miejsce zarówno przed, jak i po powstaniu złoża rudy. Zastosowanie analizy ICP-MS dla oznaczenia zawartości pierwiastków, kontrast umożliwił skuteczną ocenę względnego stopnia denudacji, jaka wystąpiła na złożu Pac Lang. Wnioski z tego badania były spójne z wcześniejszymi badaniami dotyczącymi geologii złóż rud, geochemicznym pierwotnym halo i badaniem wskaźników geochemicznych dla określenia przestrzennego rozmieszczania złóż rudy złota. W pracy przedstawiono zastosowanie analizy osobliwości do oceny stopnia denudacji, który jest ważną informacją geologiczną , która może pomóc w interpretacji danych. Wyniki badania mogą mieć także istotną wartość referencyjną w pogłębianiu naszej wiedzy na temat deformacji złóż rud oraz w badaniu nieznanych złóż rud w północno-wschodnim regionie Wietnam. Wyniki badań wskazują, że wykorzystanie analizy osobliwości do oceny stopnia denudacji jest cennym narzędziem do badania potencjalnych złóż złota i poszerzania naszej wiedzy na temat geologii złóż złota w północno-wschodnim Wietnamie. Artykuł wnosi wkład w istniejący zasób wiedzy na temat złóż złota w dorzeczu Song Hien Rift i może służyć jako przydatny punkt odniesienia dla przyszłych badań w tej dziedzinie.
