About Unnamed (Cordylite-like Calcium-Barium-Cerium Carbonate-Fluoride)Hide

Formula:
Ca◻Ba2Ce4[CO3]8F2
Formula for Z = 1.
Member of:
Cordylite Group
Isostructural with:
Cordylite-(Ce)
Originally the mineral was submitted in CNMNMN IMA in 1989 and had been approved as "Zhangpeishanite", until it was suspended by Mandarino, who felt it was Cordylite-(Ce). Indeed the mineral is connected with Cordylite-(Ce) by isomorphic replacement 2Na+ = Ca2+ + ◻ and represented on the locality by practically pure end member.
Unfortunately quite another mineral from Bayan Obo was named Zhangpeishanite recently.
