The tungsten mineralization in the Yangbishan deposit is an example of contact metasomatic，or skarn-type，mineralization.The primary lines of evidence are that（i）tungsten ore bodies occur in the contact zone between the gneissic granite and the marble of the Dapandao Formation；（ii）tungsten ore bodies are controlled by that contact zone and present as veins，lenses，or layer-like shapes；（iii）the tungsten ore has similar mineral assemblages，paragenesis，ore textures，and ore structures to the typical skarn deposit；and（iv）the skarn is closely associated with the tungsten mineralization，and the wallrock alteration occurs on both sides of the contact zone.This view is also supported by comparisons between the Yangbishan tungsten deposit and typical skarn-type tugsten deposits in China（Table 5）.
