About Florencite-(Ce)Hide

08578690017073452857121.jpg
Guilherme Florence
Formula:
CeAl3(PO4)2(OH)6
Colour:
Pale yellow to butterscotch-yellow, red-orange, pink, pale brown, colorless to gray; colorless to pale yellow in thin section, may be zoned.
Lustre:
Resinous, Greasy
Hardness:
5 - 6
Specific Gravity:
3.45 - 3.54
Crystal System:
Trigonal
Name:
Named florencite in honor of Dr. Guilherme (William) Florence (19 June 1864 - 5 October 1942), Brazilian mineralogist with the Sao Paulo Geographic and Geological Commission. He made a preliminary chemical examination of the mineral. The "-(Ce)" suffix was added in 1987 (Nickel and Mandarino), in allusion to cerium being the dominant REE in the composition.
This page provides mineralogical data about Florencite-(Ce).
