System:TrigonalColour:Yellow
Lustre:Vitreous, ResinousHardness:4½
Name:From Chinese for "a cerium mineral from China."


Bastnäsite Group.

Probably 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)

IMA status: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 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).<br /> <br /> 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.<br /> <br /> Thus we have a strange situation that we seem to have a CNMMN-approved name for a non-approved mineral.
