A possible linkage between highly fractionated granitoids and associated W-mineralization in the Mesozoic Yaogangxian granitic intrusion, Nanling region, South China

The Yaogangxian (YGX) W deposit in the central Nanling W province, South China, is one of the largest W deposits worldwide. Both vein-type wolframite and skarn-type scheelite orebodies were exposed in YGX. These scheelite and wolframite mineralization are spatially associated with the YGX granitic intrusion. The exposed intrusion contains two main intrusive phases: lower zone, coarse-grained two-mica granite and upper zone, fine-grained...
