Chlorargyrite crystals from Chañarcillo, Chile – small cabinet specimen as unique piece
This small cabinet specimen with Chlorargyrite crystals from Chile shows a striking and highly contrasting surface with brown to dark reddish brown areas intersected by greenish blue zones. The coloration is typical for secondary silver minerals and gives the specimen a vivid and characteristic appearance.
The Chlorargyrite crystals occur mainly as fine grained to crusty coatings. Individual crystals are not clearly developed, instead they form an irregularly structured matte surface. Nevertheless the crystalline nature is clearly recognizable and highlights the authenticity of this classic silver mineral.
Geology & Origin
Chlorargyrite also known as silver chloride typically forms in the oxidation zone of silver deposits. It develops through the reaction of silver bearing minerals with chloride rich solutions and is one of the most important secondary silver minerals.
The Chañarcillo mining district in Chile is one of the historically most significant silver localities worldwide. Its oxidized zones are well known for a wide variety of secondary silver minerals preserved under arid environmental conditions.
