Formula:
Pb2+Cu32+Te6+O6(OH)2
System:
Trigonal
Colour:
Green
Name:
For its relationship to Khinite
A polytype of Khinite

A polytype of khinite. The name and separate species status of "parakhinite" have been discredited (IMA-08-C), and the phase is now the polytype khinite-3T (Hawthorne et al., 2009).
