Basically in HWSN, nodes those are heterogenite
in resources are less in percentage fraction.
Minerals occurring in this leached zone included goethite, hematite, jarosite, erythrite, native bismuth, bieberite, heterogenite
, nontronite and pitticite.
Or cette heterogenite
n'est nullement egale : les gens du Sud sont plus alphabetises, plus nombreux dans la micro-elite << moderne >>, plus a meme de valoriser leurs liens internationaux, etc.
Economic mineralisation in the oxide zone ins primarily malachite, pseudomalachite and chrysocolla, with heterogenite
the main oxide cobalt mineral.
At Aghbar, conichalcite rests on transparent, elongated quartz crystals, associated with black heterogenite
. In the oxidation zone exposed in this open-pit mine, transparent deep green conichalcite spherules commonly encrust grains of chalcopyrite and chalcocite from which they have obviously formed.
There is nice malachite, dull earthy heterogenite
and crystalline copper phosphates which I still need to identify.
More rarely, cobaltarthurite is associated with arseniosiderite and heterogenite
We walked a kilometer down into the Musonoi on the backfill, and saw bits of malachite and black bubbly heterogenite
Cobalt, copper and uranium are the important ore metals in a large number of deposits within and near the "Katanga Crescent." Many beautiful cobalt-containing minerals have come from this famous area, including carrollite, cattierite, siegenite, comblainite, heterogenite
, kolwezite, oursinite, sphaerocobaltite, and brilliant pink cobaltoan calcite and dolomite.
As usual, Gilbert Gauthier's stand at the Main Show was all forest-green with Congo malachite specimens, but some of the darkest and lushest of the greens were contributed by a few miniature and cabinet-sized specimens of malachite-stained heterogenite
(a cobalt oxide/hydroxide) on chrysocolla on altered rock, from the Star of the Congo mine near the city of Lubumbashi, Katanga, Congo.
The mine has produced some excellent specimens of erythrite and heterogenite
, and also the first arsenolite and picropharmacolite reported from South Africa.
