Carlgieseckeite-(Nd)

This page is currently not sponsored. Click here to sponsor this page.
Karl Ludwig Giesecke
Formula:
NaNdCa3(PO4)3F
Colour:
Colorless with a faint greenish hue; Pink
Lustre:
Vitreous, Greasy
Hardness:
5
Specific Gravity:
3.91 (Calculated)
Crystal System:
Trigonal
Name:
Named in honour of the mineralogist and polar explorer Carl (or Karl) Ludwig Giesecke (6 April 1761, Augsburg, Germany – 5 March 1833, Dublin, Ireland) who was the pioneer researcher in the mineralogy of Greenland.
A mineral in the Belovite Group of the Apatite Supergroup. It is the first mineral of the apatite supergroup with Nd as a species-defining element.

Carlgieseckeite-(Nd) is the isostructural Nd- and Ca-dominant analogue of belovite-(Ce) and belovite-(La).
