Analysis of granitic rocks reveals U-Pb ages and geochemical characteristics, suggesting tectonic influences in the region.

Granites in the Menghewula region show Early Cretaceous zircon U-Pb ages of 135.60 ± 0.29 Ma and 134.33 ± 0.28 Ma, indicating a complex magmatic history.
The ε Hf (t) values of zircons range from 4.50 to 9.34, suggesting granitic material formed from young crustal resources influenced by depleted mantle sources.
Rocks formed in a post-collisional extensional setting, indicating a response to the subduction of the Paleo-Pacific plate during the Neoproterozoic.
The findings provide insights into the relationship between magmatic evolution and mineralization within the Paleo-Asian Oceanic domain.

Hai et al. (2025) studied this question.
