Bouazzerite is associated with quartz, chalcopyrite, native gold, erythrite, talmessite/roselite-beta, Cr-bearing yukonite, alumopharmacosiderite, powellite, and a blue-green earthy copper arsenate related to geminite. The mineral results from the weathering of a Va- riscan hydrothermal As-Co-Ni-Ag-Au vein. The Bou Azzer mine and the similarly named district have produced many outstanding mineral specimens, including the world’s best erythrite and roselite. Bouazzerite forms monoclinic prismatic {021} crystals up to 0.5 mm in length. It has a pale 3 apple green color, a colorless streak, and is translucent with adamantine luster. dcalc is 2.81(2) g/cm (from X-ray structure refi nement). -

The CuO 6 ‘octahedra’ showJahn-Teller distortion with the elongationrunning approximately along <627>. The hydrogen bonding network in the structure was characterizedusing bond valence calculations. ‘b-duftite’ isan intermediate in the duftite– conichalcite series,which has a modulatedstructure based on the intergrowth of the two structures in domains of approximately50 A Ê .Theorigin of the modulation is thought to beassociatedwith displacements in the oxygenlattice and is related to the orientation of the Jahn-Teller distortion of CuO 6 ‘octahedra’. Approximatelyhalf of the strips show an elongation parallel to <627> while the other strips are elongatedparallel to [010 ].This ordering results in an increase in the b cellrepeat compared to duftite andconichalcite.

Copyright 2003 Wiley Abstract: The application of Raman microscopy to the study of closely related mineral phases of the adelite group has enabled their molecular characterisation. The adelite group of minerals are orthorhombic arsenates and vanadates of general formula 2+ 5+ 5+ AB (XO4)(OH) where X may be As or V and cation A may be Ca or Pb; cation B may be Co or Cu and others. Raman spectroscopy has proven most powerful for the identification of these minerals. In particular the position of the hydroxyl stretching vibrations and most of the arsenate bands have been identified. The two minerals tangeite and calciovolborthite have previously been identified as the same mineral. Raman spectroscopy has proven that the minerals are not identical and have different structures. -
