Formula:
CaFe23+(PO4)2(OH,F)2
System:
Amorphous
Colour:
Yellow to yellow-brown, ...
Hardness:
2 - 3
Name:
For the type locality at Richelle, Liège Province, Belgium.
Occurs as a secondary (?) mineral in phosphatic sedimentary rocks.

Classification of Richellite

Questionable/Doubtful 1883
Explanation of status:
Probably a former gel with variable chemical composition. Other amorphous Ca-Fe-phosphates have been described in the old literature. Unit-cell parameters refer to heated material.
