Tundrite-(Nd)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Na2(Nd,Ce)2Ti(SiO4)(CO3)2O2
Hardness:
3
Member of:
Name:
Named for its relationship to tundrite-(Ce), with Nd being the dominant rare earth element.
Note that the mineral was accepted automaticaly, without detailed investigation and description of type material. Only a single Nd-dominant analysis was published. In other words, Tundrite-(Nd) is a very doubtful mineral, which nobody saw and nobody have. Consequently nobody was able to repeat results of its chemical analysis.
