Formula:
(Ce,Ca,Sr)CO3(OH,H2O)
Colour:
Colourless, white, pale pink, pink, grey
Crystal System:
Orthorhombic
Name:
From the Greek αγκυλός ("ankylos") for "curved", in allusion to its usually rounded and distorted crystal shapes, and the prefix "CALCIO-" in allusion to its composition with CALCIum dominant over strontium, plus the "-(Ce)" suffix due to cerium being the dominant REE.
