n.
A lead sulfate mineral, PbSO4, occurring in colorless or tinted crystals and formed by the weathering of lead ore.

[After Anglesey.]

anglesite

(ˈæŋɡəlˌsaɪt)
n
(Minerals) a white or grey secondary mineral consisting of lead sulphate in orthorhombic crystalline form. It occurs in lead-ore deposits and is a source of lead. Formula: PbSO4
[C19: from Anglesey, where it was first found]

n.
a mineral, lead sulfate, PbSO4, found in massive deposits and in colorless or variously tinted crystals: a minor ore of lead.

Galena, Cerrusite and Anglesite are the three most important ores that are mined.
(1) Low-temperature sulfur incrustations from Ebeko volcano contain appreciable amounts of trace elements stored in rock particles, metal sulfides (e.g., argentite ([Ag.sub.2]S), covellite (CuS), cadmoindite (Cd[In.sub.2][S.sub.4]), famatinite ([Cu.sub.3]Sb[S.sub.4])), chlorides (cotunnite (Pb[Cl.sub.2])), sulfates (anhydrite (CaS[O.sub.4]), alunite [(K[Al.sub.3](S[O.sub.4]).sub.2][(OH).sub.6]), anglesite (PbS[O.sub.4]), barite (BaS[O.sub.4])), and tungstates (scheelite (CaW[O.sub.4])).
The LCMT was the residual of dressing Pb crude ore from the Bo Ngam mine (around 10 km from the facility) consisting of galena (PbS), cerrusite (PbC[O.sub.3]), and some anglesite (PbS[O.sub.4]) in limestone, clay, and quartz matrices.
Galena generally oxidizes to cerussite (PbC[O.sub.3]) and anglesite (PbS[O.sub.4]).
"It emerged that the sulphate anions had found a suitable reaction partner in lead ions from the varnish and had formed anglesite," explains DESY scientist Gerald Falkenberg.
Anglesite (PbSO4) is an opaque compound that was found nearly everywhere throughout the varnish.
They found that cadmium ions from the oil paint had combined with bits of the varnish itself to make a compound called cadmium oxalate, while sulphate ions from the paint interacted with lead from the varnish to make a compound called anglesite. Together, the cadmium oxalate and anglesite account for the discoloration.
(2001) identified both PbS[O.sub.4] (anglesite) and metallic Pb in soil from this site.
Within the oxidized zones, the primary sulfide minerals were commonly converted to limonite, pyrolusite, cerussite, anglesite, argentojarosite and plumbojarosite (basic sulfates of Fe), and native silver, with traces of malachite and azurite.
