These include arseniosiderite, bromargyrite, cabalzarite, chalcophyllite, clinoclase, clinotyrolite, cobaltkoritnigite, cornubite, fornacite, geminite, litharge, mottramite, nickellotharmeyerite, novacekite, parnauite, powellite, uvarovite, walentaite, wulfenite, yukonite and zalesiite.
See under Cornubite, Cornwallite, Clinoclase and Strashimirite.
Occasionally in the same matrix there are microcrystals of clinoclase
peeping out of tiny vugs.
Extensive collecting at the abandoned mines has revealed over 65 mineral species in a complex polymetallic quartz vein system, including bismutoferrite, bismutostibiconite, clinobisvanite, koechlinite, namibite, schumacherite, posnjakite, wroewolfeite, idaite, cornwallite, clinoclase
, cornubite and lindgrenite.
The Smale/Royal Society exhibit included the world's best liroconite and the world's best clinoclase
"ball" of dark green crystals on matrix, as well as superb specimens of chalcocite, langite, olivenite, cornwallite and bournonite.
Good specimens of erythrite and clinoclase
microcrystals were discovered in the Freirina area near Vallenar in 2000.
Arseniosiderite has recently been found at the Gambatesa mine in fractures in chert, as yellow to brown rosettes up to 2 mm, associated with clinoclase.
Clinoclase has been found as blue crystals up to 3 mm at the Gambatesa mine in association with arseniosiderite in chert fractures.
Seven chemical analyses were carried out by means of an electron microprobe using the following standards: clinoclase
for Cu and As, hematite for Fe, Bi metal for Bi and wollastonite for Ca.
Relationship to other species: A polymorph of clinoclase
These include scorodite, chalcophyllite, connellite and clinoclase
619-941-2848) did some very successful collecting two and a half years ago at the Majuba Hill mine in Pershing County, waiting until now to show us the resulting handful of excellent small specimens of clinoclase
