Short summary
Wumuite, ideally KAl0.33W2.67O9 with a hexagonal tungsten bronze (HTB)-type structure, is another new mineral containing potassium and tungsten found in the Pan–Xi region in China after tewite was discovered. In this study, artificial synthetic experiments have been conducted to explore the formation process of wumuite and tewite. Wumuite was speculated to be formed by a metasomatic reaction between W-rich hydrothermal fluids and the potassium feldspar in the monzonite.
