Environments
Claringbullite occurs in oxidised copper ore or slag, produced under
chlorine-rich conditions (Webmin, HOM).
Associated minerals include cuprite,
malachite,
quartz, brochantite,
nantokite, paratacamite,
connellite and spangolite
(HOM).
Localities
There are two co-type localities, the M'sesa mine, Kambove District, Haut-Katanga, DR Congo, and the Nchanga mine,
Chingola,
Chingola District, Copperbelt Province, Zambia.
At the M'sesa mine, DR Congo, claringbullite has been found as slightly divergent groups of soft blue plates up
to 1 mm across in
a vug in cuprite, associated with crystals of
brochantite.
Malachite and copper occur
elsewhere on the specimen
(MM 41.433-436).
At Bisbee, Arizona, USA, claringbullite occurs very rarely in association with
cuprite
nodules (Minrec supplement to 43.1, page 14). Dick Graeme has in his Bisbee collection a superb specimen 5 cm
across of
claringbullite crystals
(Minrec 37.2.177).
At the Nchanga mine, Zambia, claringbullite has been found as a slightly divergent group of blue plates filling
a cavity in
quartz and malachite on
cuprite. Quartz crystals also occur on
the specimen
(MM 41.433-436).
