Zhonghuacerite-(Ce)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ba2Ce(CO3)3F
System:
Trigonal
Colour:
Yellow
Lustre:
Vitreous, Resinous
Hardness:
Name:
From Chinese for "a cerium mineral from China."
Bastnäsite Group.

Not valid, type material may be either Huanghoite-(Ce) or Kukharenkoite-(Ce). Formula and the revised monoclinic cell parameters seen in e.g. webmineral.com (from Dana 8?) suggest identity with kukharenkoite-(Ce).

Originally reported from West Mine, Bayan Obo (Bayun-Obo; Baiyunebo) deposit, Darhan Muminggan United Banner, Baotou League, Nei Mongol Autonomous Region (Inner Mongolia), China.

Classification of Zhonghuacerite-(Ce)

Published without Approval
Explanation of status:
The so called zhonghuacerite-(Ce) was never submitted to the IMA CNMMN hence it was never approved. It entered the mineralogical literature via a review in the New Minerals section of Am. Min. 67, 1078. The description was published in Chinese and the reviewer was not aware that the mineral was not approved by IMA. The mineral was listed in the Glossary of Mineral Species (Fleischer 1983 and Fleisher and Mandarino 1995).

Zhonghuacerite was published in 1981 without having been submitted to the CNMMN. The name was changed by the CNMMN in 1987 to zhonghuacerite-(Ce) as part of the update of mineral names with Levinson modifiers, without realizing that it was an unapproved mineral and mineral name. Officially this species does not exist.
