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.[2]
