The recent finds of pargasite/ "fluor-cannilloite" from "Yuang Yang (Yueng Yang), Wenshan, Yunnan Province, China" are really from this locality.
Yuang Yang is in fact a small city in Yunnan Province where mineral dealers frequently offer Vietnamese specimens.

There are numerous quarries spread along a 12 km line in this area, all generally labelled "Luc Yen", although some should probably be renamed.

NOTE: All of the analysed 'fluor-cannilloites' are pargasite (see http://www.mindat.org/mesg-106-259756.html, http://www.mindat.org/mesg-7-69925.html and http://www.mindat.org/mesg-7-198029.html). Hauzenberger et al. (2005) report intense green pargasite in association with red spinel from Luc Yen. This pargasite has been confirmed by EPMA and single-crystal XRD.

Alternative Label Names

This is a list of additional names that have been recorded for mineral labels associated with this locality in the minID database. This may include previous versions of the locality name hierarchy from mindat.org, data entry errors, and it may also include unconfirmed sublocality names or other names that can only be matched to this level.
