Chlorargyrite is a secondary mineral found in the oxidation
silver deposits, especially in arid regions, and in
epithermal (low temperature) veins. It is
found associated with native silver,
cerussite and other
At the Broken Hill district, Yancowinna county, New South Wales, Australia, the deposit originally formed in a shallow lake or submarine rift and now comprises an intensely granulite and upper amphibolite facies metamorphosed and deformed sequence of sedimentary and volcanic rocks, and minor iron-rich and
Chlorargyrite occurs in vuggy coronadite with goethite, sometimes associated with smithsonite. It is also found with cerussite, dolomite and malachite. At deeper levels it is a late-stage mineral in the arsenate zones, associated with carminite and members of the segnitite to beudantite series (AJM 3.1.34).
At the San Rafael Mine, Quartz Mountain camp, Lodi Mining District, Lodi Hills, Nye County, Nevada, USA, chlorargyrite and bromargyrite occur sparingly, associated with mimetite, anglesite and bayldonite (R&M 85.6.516).
