About Dissakisite-(Ce)Hide

Formula:

(CaCe)(AlAlMg)O[Si₂O₇][SiO₄](OH)

Colour:

Pale yellow-brown in thin section.

Lustre:

Vitreous

Hardness:

6½ - 7

Specific Gravity:

3.75

Crystal System:

Monoclinic

Member of:

Allanite Group > Epidote Supergroup

Name:

Named in 1991 by Edward S. Grew, Eric J. Essene, Donald R. Peacor, Shu-Chun Su, and Masao Asami from the Greek for twice over, for a second magnesium analog of allanite being described. The suffix follows the Levinson rule for minerals with essential REE (and the nomenclature for epidote-group minerals); denoting predominant cerium.

Type Locality:

ⓘ Balchen Mt, Sør Rondane Mountains, Queen Maud Land, Eastern Antarctica, Antarctica

Chemically related to dollaseite-(Ce), gatelite-(Ce), manaevite-(Ce), västmanlandite-(Ce), and somewhat to khristovite-(Ce).

Dissakisite-(Ce) often contain a significant portion allanite-(Ce), intermediate compositions and zoned crystals are common.
