Chlorargyrite

Halide

Chlorargyrite is the mineral form of silver chloride (AgCl). Chlorargyrite occurs as a secondary mineral phase in the oxidation of silver mineral deposits. It crystallizes in the isometric - hexoctahedral crystal class. Typically massive to columnar in occurrence it also has been found as colorless to variably yellow cubic crystals. The color changes to brown or purple on exposure to light. It is quite soft with a Mohs hardness of 1 to 2 and dense with a specific gravity of 5.55. It is also known as cerargyrite and, when weathered by desert air, as horn silver. Bromian chlorargyrite (or embolite) is also common. Chlorargyrite is water-insoluble.

It occurs associated with native silver , cerussite, malachite

It was first described in 1875 for occurrences in the Broken Hill, Australia. The rich Bridal Chamber deposit at Lake Valley, Sierra County, New Mexico was almost pure chorargyrite. The name is from the Greek, chloros for "pale green" and Latin for silver, argentum.
