...E. Makovicky; D. Topa Abstract Electron microprobe analysis of barikaite ( Topa et al. , 2013 ) indicates the chemical formula Ag 2.90 Tl 0.04 Pb 9.31 As 11.26 Sb 8.12 S 40.37 . Barikaite is monoclinic, with a 8.533(1) Å, b 8.075(1) Å, c 24.828(2) Å, and β 99.077(1)°; unit-cell volume 1689.2 Å 3...

...D. Topa; E. Makovicky; H. Tajedin; H. Putz; G. Zagler Abstract Barikaite, ideally Pb 10 Ag 3 (Sb 8 As 11 ) Σ19 S 40 , is a new mineral species from the Barika Au-Ag deposit, Azarbaijan Province, western Iran. It was formed in fractures developed in silica bands situated in massive banded pyrite...

... is an (Ag,Sb)-rich homeotype of dufrénoysite, stabilized by the complete coupled substitution 2 Pb 2+ = Ag + + Sb 3+ on a specific site of the crystal structure. Together with barikaite, it belongs to the rathite sub-group of P 2 1 / c homeotypes of dufrénoysite, of which the crystal chemistry is discussed...

.... Veenite, polloneite, dufrénoysite and barikaite (all of which are N = 4 homologues of sartorite; Table 6 ) can be compared using plots of cation-anion populated surface layers of the double-layer segments from their structures ( Figs 4 – 6 ). For these comparisons, we have to name the four columns...

...). The discovery of a new locality of As-Sb sulfosalts at Barika in the Azarbaijan Province of western Iran ( Khodaparast et al. , 2010 ) led to the description of another As-Sb member, barikaite ( Topa et al. , 2013 ). Thallium was found to participate in the composition of several members of the series...
