2], and hydrocerussite
were in common use among artists in the early 20th century.
An outcrop of the Roughton Gill South vein in the higher reaches of the gill has recently yielded some good specimens of matthed-dleite in minute needles with caledonite, lanarkite, leadhillite and hydrocerussite
Lead phases detected by X-ray d iffraction include synthetic hydrocerussite ([Pb.
A sample from the outside of a home built in Rome, Georgia in 1933 contained the lead pigment synthetic hydrocerussite ([Pb.
Fine examples of cerussite, dioptase, malachite, azurite, wulfenite, smithsonite and vanadinite have been collected there, as well as some of the finest known examples of a number of rarer species such as boleite, diaboleite, caledonite, hydrocerussite
, linarite, matlockite and leadhillite.
Cerussite is an extremely rare, late-stage alteration product, occurring as white powdery coatings or tan crusts, sometimes admixed with hydrocerussite
, on galena crystals in the lower sill.
Rarities such as hydrocerussite
, diaboleite and leadhillite were fun to see, and caused many an Arizona collector's pulse to quicken.
Associated minerals are: cerussite, hydrocerussite
, paralaurionite, blixite, chloroxiphite, pyrolusite, coronadoite, hematite, parkinsonite and mereheadite.
There was also a Tsumeb array, with fine small specimens of mimetite, smithsonite and hydrocerussite
and rare allactite have also been noted in this assemblage.
The mine is the type locality for the minerals chloroxiphite and diaboleite, and has also produced some of the largest known crystals of hydrocerussite
, ludlockite, schneiderhohnite (
