  • Paratacamite - Wikipedia

    en.wikipedia.org/wiki/Paratacamite Paratacamite is a mineral in the halide minerals category. Its chemical formula is Cu 3 (Cu,Zn)(OH) 6 Cl 2. Its name is derived from its association with atacamite. It is found in Chile, Botallack Mine in Cornwall, Broken Hill, Australia, and in Italy in Capo Calamita on the island of Elba.

A “fingerprint” on the powder XRD pattern for distinguishing paratacamite from clinoatacamite is appear-ance of diffraction peaks at a spacing of 28 nm d 22 nm corresponding to 32° 2 41° for Cu K radia-tion.

  • Atacamite - Wikipedia

    en.wikipedia.org/wiki/Atacamite Atacamite is polymorphous with botallackite, clinoatacamite, and paratacamite. Atacamite is a comparatively rare mineral, formed from primary copper minerals in the oxidation or weathering zone of arid climates. It has also been reported as a volcanic sublimate from fumarole deposits, as sulfide alteration products in black smokers.
