Secondary minerals consist of lead minerals like anglesite, cerussite, pyromorphite and wulfenite, and of iron sulfides like marcasite and pyrite.
22.
Associated secondary minerals include cerussite, phoenicochroite, vauquelinite, willemite, wulfenite, galena, sphalerite, pyrite, tennantite and chalcopyrite.
23.
The region is known for striking combinations of cerussite, fluorite, vanadinite, wulfenite, barite, and mimetite, as well as galenite and anglesite.
24.
A number of small mining districts are located in the hills around Villa Ahumada, and the area is noted for its crystal specimens of wulfenite and other minerals.
25.
Lesser known localities of wulfenite include : Sherman Tunnel, St . Peter s Dome, Tincup-Tomichi-Moncarch mining districts, Pride of America mine and Bandora mine in Colorado.
26.
When massicot is found in a natural environment, some other minerals that may be found with it may include cerussite, litharge, minium, wulfenite, oxides of antimony and limonite.
27.
It occurs in the oxidized zone of ore deposits and is associated with dioptase, wulfenite, hemihedrite, phoenicochroite, duftite, mimetite, shattuckite, chrysocolla, hemimorphite, willemite and fluorite.
28.
The structure of the wulfenite-" I " 4 1 / a system can be described as a close packing of tetrahedral MoO 4 2 " anions and Pb 2 + cations.
29.
The correct nomenclature of the 90 : 10 solid state is wulfenite-" I " 4 1 / a and the 64 : 36 solid state is wulfenite-" I " 4.
