About Tundrite-(Ce)Hide

Yellow-brown, green-yellow
Greasy, Silky
Crystal System:
Member of:
Originally called titanorhabdophane. Named tundrite after the Lovozero tundra, by E. I. Semenov in 1963. The suffix was added later, following the Levinson rule, to indicate the dominant rare earth element.
Closely related to kihlmanite-(Ce).
