Petrogenesis of the Yupo W-bearing and Dali Mo-bearing granitoids in the Dayaoshan area, South China: Constraints of geochronology and geochemistry

The geological significance of Early Paleozoic (Caledonian) magmatism and associated mineralization in South China is, as yet, poorly understood compared to the well-documented Mid-Late Mesozoic (Yanshanian) magmatism and associated mineralization. The Early Paleozoic granitoids were previously thought to be rarely mineralized. Both Caledonian granitoids and Yanshanian granitoids occur in the Dayaoshan area from the Qin–Hang metallogenic belt,...
