Geochronology and geochemistry of granitoids related to the giant Dahutang tungsten deposit, middle Yangtze River region, China: Implications for petrogenesis, geodynamic setting, and mineralization

Porphyry and skarn deposits in the middle Yangtze Valley within the Northern Yangtze Craton have a combined tungsten resource of ~ 3 million tonnes (Mt) and represent one of the most important tungsten regions in the world. The Dahutang porphyry tungsten deposit, with reserves of > 1 Mt, is one of the largest deposits. Uranium–Pb analyses for the ore-related granitoids yield ages of 147.4 ± 0.58 Ma–148.3 ± 1.9 Ma for porphyritic biotite granite,...
