...Halil Sarp; Radovan Černý; Hakki Babalik; Murat Hatipoğlu; Gilbert Mari Abstract Lapeyreite, ideally Cu 3 O[AsO 3 (OH)] 2 ·0.75H 2 O, was found in the old copper mines of Roua (Alpes-Maritimes, France). It is invariably in intimate association with trippkeite. Other associated minerals...

.... The structure of jacquesdietrichite bears the closest resemblance to that of trippkeite, Cu(As 2 O 4 ). The structure of jacquesdietrichite projected along [001] ( Fig. 5 ) appears quite similar to that of trippkeite projected along [100]. The structure of trippkeite has large channels along [001] (the chain...

.... To the best of our knowledge, no other mineral displays a combination of As 2 O 5 dimers and (As 3+ O 2 chains. Minerals showing infinite (As 3+ O 2 chains are only leiteite ( Ghose et al. , 1987 ) and trippkeite ( Pertlik, 1975 ). The first has the closest structural similarities with karibibite...

... and 89.3° to 106.6°, the respective mean values are between 1.76 to 1.80 Å and 94.8° to 102.8°. In addition, in trippkeite, CuAs 2 O 4 , the As-O distances are: 1.89(×2) and 1.69 Å (av. 1.82 Å) (Zemann, 195l). In nanlingite the individual As-O distances (1.73–1.78 Å), <As(1)-O> (1.78 Å...

.... Qualitative examination showed only Cu and As. For quantitative analysis, trippkeite (Cu, As), copper metal (Cu) and arsenic metal (As) were used as standards. The results are given in Table 1. Table 1. Chemical analysis [wt.%] of rollandite. The H 2 O was estimated by difference due...

..., Andreas Karlsson and Muriel Erambert) Proposal 23-C is accepted and the minium group is defined. The group consists of five valid members: minimum, Pb 4+ Pb 2+ 2 O 4 , trippkeite, Cu 2+ As 3+ 2 O 4 , schafarzikite, Fe 2+ Sb 3+ 2 O 4 , igelströmite, Fe 3+ (SbPb)O 4 , and the newly approved species...

... ), whereas pentamers were observed in ludlockite, PbFe 4 As 10 O 22 (Cooper and Hawthorne, 1996 ). Infinite chains have been reported in trippkeite, CuAs 2 O 4 (Pertlik, 1975 ) and leiteite, ZnAs 2 O 4 (Ghose et al. , 1987 ). Species containing (As 2 O 5 ) dimers are relatively more common.
