Member of:
Name:
Named in 1823 by August Breithaupt after the type locality - Ľubietová (Libethen in German, Libetbánya in Hungarian), Slovak Republic. Prior to 1919, the locality was in the territory of Hungary.
Polymorph of:
Olivenite Group. Libethenite-Olivenite Series.
Compare zincolibethenite.
Libethenite is a secondary copper phosphate mineral found in the oxidized zone of copper ore deposits. The phosphate is often derived from the weathering of apatite and other rock-forming phosphates such as monazite and xenotime.
A rare case of probable primary libethenite from a greisen deposit is reported by Sejkora et al. (2006).
