Synchysite-(Ce) is a carbonate mineral and an end member of the synchysite group. The general chemical formula is Ca(Ce,La)(CO
3)
2F.[3]
Discovery and naming
Synchysite-(Ce) was discovered in 1900 by Gustaf Flink.[4] The name is derived from the Greek "σύγχΰσις", meaning "confounding", a reference to the possibility to confuse the mineral with Parisite-(Ce).
Occurrences
Synchysite-(Ce) is found in rare-earth element bearing pegmatites.[5] It can also occur as a hydrothermal mineral in granite, alkalic syenite and carbonatite.[1]
