Catapleiite was first described for an occurrence in Låven (Skådön; Lamö; Lamanskjaer), Langesundsfjorden, Larvik, Vestfold, Norway. The name "Catapleiite" was derived from the Greek word "Kata" and "Pleion" which means "With" and "More" respectively. This name was given for its relation with many other rare minerals.

Formation Process

Most of the Catapleiite occurs as a thin tabular yellow or yellowish-brown crystals. It commonly occurs in pegmatite after the alteration of eudialyte and in syenites and nepheline syenites. 


The chemical formula of Catapleiite is Na2Zr(Si3O9) · 2H2O. It has a hardness of 5.5-6 according to the Mohs scale.


Catapleiite has no type of its own.
