# Age and Source of the Jinjingzui Skarn-Type Gold Deposit in the Southeastern Hubei Province, China
## 5 Discussion
### Implications of Regional Mineralization  
[PERSON] et al. (2006, 2008) proposed that two significant mineralization events occurred in the Middle-Lower Yangtze River Valley, with mineralization ages concentrated in the ranges of 132-145 Ma and 123-125 Ma. The mineralization in the southeastern Hubei ore cluster primarily occurred during the first event [9; 42; 43]. The rock-forming and mineralization processes exhibit a clear temporal correlation, indicating their coeval formation. Zircon U-Pb dating (141 Ma) and molybden Re-Os dating (138.5 Ma) demonstrate that the Jinjingzui gold deposit formed during the Early Cretaceous, contemporaneous with other skarn-type deposits in southeastern Hubei and the broader Middle-Lower Yangtze River Valley [14]. This chronological consistency suggests these deposits share a common tectonic setting (Table 5). \begin{table}
