Yaogangxian Mine, Chenzhou, Hunan Province, China | |||||
Small Cabinet | 7.5x6x6cm | 365g | |||
Dominant on this specimen are large but damaged xls of ferberite, fluorite, arsenopyrite and quartz. Most remarkable is however a seam of reddish brown cassiterite xls to 0.8cm, located between the ferberite and the arsenopyrite. Cassiterite is considered being a rare species at Yaogangxian, and the xls, although fairly large, well developed and undamaged, cannot meet the standards of Yunnan or Sichuan locations. On the other hand are cassiterite specimens often misattributed to famous locations, such as Yaogangxian! | |||||
