Huebnerite is the manganese-rich end member, and Ferberite is the iron-rich end member. The term Wolframite can be used generally to describe unspecified members of this group, or to describe the intermediary member of this series. Wolframite is named for its tungsten content, since wolfram means tungsten in German. Chemical Formula. (Mn,Fe)WO4 ...

In this study, we present the first laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U–Pb geochronological analysis of wolframite samples. The lack of a matrix-matched wolframite standard is the major limitation of its in situ geochronological analysis. Therefore, the matrix effects between zircon and wolframite …

There are only three ideal end-member compositions possible in the wolframite group. These are MnWO 4 ( huebnerite ), FeWO 4 ( ferberite ), and ZnWO 4 ( sanmartinite ). Wolframite, the mineral for which the group is named, comprises the range of compositions from (Mn 0.2 Fe 0.8) WO 4 to (Mn 0.8 Fe 0.2 )WO 4. In other words, the Mn: Fe ratio in ...

Wolframite. Wolframite (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and huebernite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.

The Baishitouwa deposit is a medium-scale quartz–wolframite vein-type deposit in the southern Great Xing'an Range tungsten (W) belt. The W mineralization occurs mainly as veins and dissemination within the mica schist of the Mesoproterozoic Baiyunebo Group. The formation of the deposit can be divided into four stages. The wolframite …
