Florencite-(Nd)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
NdAl3(PO4)2(OH)6
Hardness:
5 - 6
Name:
Named for its relationship to florencite-(Ce), with the "-(Nd)" suffix in allusion to neodymium being the dominant REE in the composition.

The root florencite, is named in honor Dr. William Florence (1864-1942), who made a preliminary chemical examination of florencite-(Ce).
This page provides mineralogical data about Florencite-(Nd).
