Description
Comments:	Data presented by Chen (1981) show a significant excess of manganese over iron (Fe:Mn ranging from 1:4 to 3:4) in all analyzed samples of wolframite from the vein-type ore bodies. Ottens and Cook (2005) however state that wolframite is predominantly ferberite and hübnerite was only found in one single pocket, suggesting that their samples came mainly (all ?) from the skarn-type ore bodies.
Quality of samples:	not specified / average specimens
Confirmation
Validity:	Believed Valid
