A fluorite mine. According to Ottens, all specimens previously attributed to the "Wushan Fluorite mine" really come from this mine, which is located near Wushan town. Liu gives the locality more precisely as Wushan town, 25 km north of De'an city, the administrative seat of De'an county. A "Wushan mine" does not appear to exist.

Notes:
1) For the octahedral blue-green fluorite etched from quartz (using HF) Bert Ottens states that the true locality is, "Ganzhou area, about 500 km south of De'an, but still in Jiangxi Province. The region is easy to reach from Chenzhou, about 200 km west of it. For now "Ganzhou" must suffice as the locality designation." The locality for the purple cubo-octahedral fluorite etched from quartz is: De'an fluorite workings at Wushan, near De'an, De'an County, Jiangxi Province (originally falsely listed as from Yiwu in Zheijiang Province). Ottens also explains that fluorite dealers in Chenzhou are intentionally not providing precise locality info.

2) Octahedral fluorites labeled as coming from here may actually come from a mine near Shangrao (see http://www.mindat.org/mesg-7-88672.html)

Numerous fluorite photos attributed to this locality will eventually need to be moved to other localities.
