About Philipsburgite
Formula:
Cu5Zn(AsO4)(PO4)(OH)6 · H2O
Cu:Zn ratio is roughly 2.5:1 - 3:1.
Colour:
Bright emerald green
Lustre:
Vitreous
Hardness:
3 - 4
Specific Gravity:
4.07
Crystal System:
Monoclinic
Name:
Named for the town of Philipsburg, Montana, USA, near the type locality.
The As-P ordered arsenate-phosphate analogue of kipushite (phosphate endmember) and goldhillite (arsenate endmember, approved in 2021).
NOTE: Many "philipsburgites" from localities except the type locality are probably goldhillite. For example, the first find of "philipsburgite" from the Clara mine, Black Forest, Germany, was analysed as P-free, i.e. it is in fact goldhillite.
Type philipsburgite shows an ordered distribution of As and P over two symmetrically independent tetrahedrally coordinated sites and, therefore, is was redefined by IMA in March 2021 with the new crystal-chemical formula Cu5Zn(AsO4)(PO4)(OH)6.H2O.
May be confused with lenticular forms of zincolivenite.

IMA Classification of Philipsburgite
Approved
IMA status notes:
Redefined by the IMA
First published:
1985
Approval history:
Originally defined as a pure arsenate. Redefined by IMA March 2021 (IMA 20-G), when it was recognised that the (P-rich) type material has an ordered distribution of As and P.
