Chlorargyrite [SEP] named after
Chlorargyrite
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
, analcime crystals ("Andreasberger Tautropfen"), pink apophyllite, scherbenkobalt (native arsenic), ganomatite ("Gänsekötigerz") breithauptite, native antimony, chlorargyrite ("Buttermilcherz") and others. The very rare mineral samsonite was named after the pit.
