Description
A naturally occurring mineral composed of lead sulfate. Anglesite occurs naturally as an oxidation product of galena (lead sulfide). First recognized as a mineral in 1783 by Dr. Withering in the Anglesey copper mine, anglesite is now mined in England, Wales (Anglesey), Scotland (Leadhills), Italy (Sardinia), Australia, Mexico (Chihuahua), and the United States (Pennsylvania, Idaho, Nevada). Anglesite is a lustrous white to colorless stone that can be transparent or opaque. It is primarily used as an ore source for lead. White crystals of anglesite also occur as a lead corrosion product (Selwyn 1996).
Synonyms and Related Terms
lead sulfate; lead vitriol; anglésite (Fr.); anglesita (Esp.); anglesite (Port.); Anglesit (Deut.); anglesiet (Ned.)
Other Properties
Slightly soluble in water.
Orthorhombic systems usually occurs as thin tabular crystals. Cleavage is good in one direction, distinct in a second direction.
Fracture - conchoidal. Luster = adamantine. Streak = white to grayish.
