Chlorargyrite is a mineral composed primarily of silver chloride (AgCl). It typically forms in the oxidation zones of silver deposits and is often found in a range of colors, including yellow, green, and brown. This mineral is also known as "horn silver" due to its metallic luster and can appear in both crystalline and massive forms. Chlorargyrite is significant in the mining industry as it serves as an important ore of silver. Its presence can indicate the proximity of silver-rich deposits, making it valuable for prospectors. The mineral is often studied for its unique properties and role in the formation of silver ores.
