Bushmakin (1947-1999) who made significant contributions to the mineralogy of the oxidized zone of the Berezovskoye deposit.
(2002) Bushmakinite P[b.sub.2]Al(P[O.sub.4])(V[O.sub.4])(OH), a new mineral of the brackebuschite group from the oxidized zone of the Berezovskoye gold deposit, the middle Urals.
Chinese antimony deposits of the Wuling type generally contain stibnite as the main ore mineral (with stibiconite and valentinite in the oxidized zone), plus quartz, barite and calcite.
Stibiconite is a common secondary mineral in the oxidized zones of the Wuling mine, where it occurs as partial or complete replacements of stibnite crystals.
Mimetite and wulfenite have long been considered rare in the oxidized zone at Broken Hill, New South Wales, and specimens are highly prized by collectors.
Although mining at the Kintore Opencut has shown mimetite to be abundant in some areas of the Broken Hill oxidized zone, Broken Hill mimetite specimens have always been quite rare in collections.
Chalcophanite occurs in an oxidized zone
of the Brick 2 as metallic black drusy coatings on a gossan matrix, as minute tabular plates, and occasionally as pseudo-octahedral or (more correctly) trigonal dipyramidal crystals to I mm.
The exploration drilling program for the next 3-6 months is designed to target favourable known horizons within the north and south extensions along strike from the Sihayo resource, primarily targeting shallow oxidized zones
. The northern limit of the regolith mineralisation is not defined.
His studies of the petrology and mineralogy relating to the oxidized zones
of base metal and precious metal deposits will be used by geologists far into the future.
Three of the most promising gold-bearing properties in the north of Haiti have a combined gross value of over $3 billion in their easily leachable oxidized zones
and underlying auriferous sulphide ores are also present.
