.... Cupromakopavonite is the N = 4.5 member of the newly defined cupropavonite homologous series, and its name underscores its close structural relationships to its two neighboring members, cupromakovickyite (N = 4) and cupropavonite (N = 5). We define the structural and chemical properties of this series...

Compositional scheme for pavonite homologues (void symbols) and cupropavonite homologues (solid symbols) in the Ag – Bi – (Cu + Pb) diagram. Lines for pavonite homologues of the order Np are indicated by points at 0, 25, 50, 75 and 100 at.% of imaginary (Ag+Bi)-for-2Pb substitution by Pb in the octahedral cation sites, for Cu-free cases. Points indicating Np values for the homologues of cupropavonite are situated on the ideal composition line for this series. Electron-microprobe data for the exsolution pairs are plotted into the scheme: makovickyite – cupromakovickyite from Băiţa Bihor, makovickyite – cupromakopavonite from Felbertal, pavonite – cupropavonite from the Alaska mine, Colorado, [1: Karup-Møller & Makovicky (19790 and 2: this work], benjaminite – cuproplumbian benjaminite from Erzwies (Makovicky et al. 2010), and mummeite – cuproplumbian mummeite from the Alaska mine (this work). Abbreviations: Np: pavonite homologue with order value N, cupro-Np: cupropavonite homologue with order value N, lam: lamellae, hg: homogeneous.

Compositions of Cu-free Pb-substituted Ag–Bi pavonites, and those of the cupropavonite series (the latter form a separate sequence of discrete homologue compositions) in the empirical Ag–Bi–(Pb+Cu) diagram. The indicated homologue order N values are valid for the Ag–Bi end-members and for the hypothetical Pb–Bi end-members of the pavonite series; they are given separately for the compositions of the cupropavonite series in the interior of the triangular diagram.

BSE photographs of exsolution aggregates involving members of the pavonite and cupropavonite homologous series. (a) Makovickyite – cupromakovickyite aggregate from Băiţa Bihor, Romania; (b) pavonite – cupropavonite aggregate from the Alaska mine, Colorado, U.S.A.; (c) benjaminite – cuproplumbian benjaminite aggregate from Erzwies, Austria (Makovicky et al. 2010); (d) mummeite – cuproplumbian mummeite aggregate from the Alaska mine, Colorado. In each image, the differences in the thickness of exsolution lamellae are primarily caused by their orientation. The length of the bars is 100 μm.

The hypothetical structure of cupropavonite projected along b (~ 4 Å). In order of increasing size, circles represent Cu (red), Bi (white), Ag (green), Pb (blue) and S (white) positions. Void and shaded circles represent atoms at two y levels, 2 Å apart. Two types of 5P thicker layers (grey shading) are separated by asymmetric thin cupromakovickyite-like layers (unshaded).

Configuration of thicker layers of octahedra in the pavonite homologues. Large circles: S, smaller circles: cations. The order of the homologue Np is determined by the number of octahedra along a diagonal of the layer. The known examples from the cupropavonite homologous series follow the same pattern.

... material allowed us to recognize a doubled c parameter of the (Cu, Pb)-rich variety. In analogy with the pair pavonite–cupropavonite (both with N = 5), the name of the (Cu, Pb)-poorer phase, makovickyite ( Žák et al . 1994 ), was used to give the name cupromakovickyite to the new, (Cu, Pb)-rich...

... distributed as lamellae down to few unit cells in thickness. It is for this reason that the Pb content reported is lower than expected. Cupromakovickyite is related to makovickyite in exactly the same way as cupropavonite is related to pavonite ( Karup-Moller & Makovicky 1979 ). In order...

... . The pairing of square coordination pyramids of Bi with bicapped coordination prisms of Pb leads in these slices to a structural analogy with cupromakovickyite and cupropavonite rather than to that with pavonite, in which only paired Bi pyramids occur in the thin, non-accretional layers ( Topa et al. 2006...
