Atacamite Group. A secondary copper mineral formed through the oxidation of other copper minerals, especially in arid, saline conditions.

Atacamite, green, brilliant halide mineral, basic copper chloride [Cu2 (OH)3Cl]. It is a secondary mineral, formed by the oxidation of other copper minerals, particularly under arid conditions; it is widespread as brittle, transparent to translucent crystals in Atacama Province, Chile; in Boleo,

2020年12月12日 · Atacamite is a rare secondary basic copper chloride, famous for its striking deep green color. It forms highly aesthetic crystals and belongs to popular specimens among secondary minerals collectors.

2008年5月27日 · The presence of large amounts of atacamite in oxide zones from ore deposits in the Atacama Desert of northern Chile requires saline solutions for its formation and hyperarid climate conditions for its preservation.

Atacamite is a comparatively rare mineral, formed from primary copper minerals in the oxidation or weathering zone, in arid climates or in coastal outcrops. Found at many localities mostly as green micro crystals. The great exceptions are the “green sticks” that were found at the New Cornwall mine in South Australia.

Atacamite Definition. Atacamite is a green-colored halide mineral. It draws its name from the fact that it originates in the Atacama Desert in Chile. Atacamite History. This mineral species was first discovered in 1801 at Atacama Region in Chile. This substance was added to the mineral species in the same year by D. de Gallizen. Atacamite Synonyms
