... and ferrilotharmeyerite are very similar; the main difference is the size of the M2 octahedron (Table 7 ). The diffraction pattern of CABA11.5 did not reveal any kind of twinning. Most (85%) of the spots could be explained in the cell given in Table 4 , but some of them were somewhat smeared out, mainly in the ( a*,c...

Compositionally, this botryoidal mass is composed of an intimate intergrowth of two distinct phases: one conforms to the composition of ferrilotharmeyerite; the other may...

...(90,422,314), and 1.775(50,533,026). The mineral occurs within a 3 cm vug at the 31 st level of the Tsumeb mine, Namibia. It is intergrown with ferrilotharmeyerite and another mineral, possibly cuprian, zincian ferrilotharmeyerite or the Zn-dominant analog of lukrahnite. The new mineral name is for Terry...

.... Occurrence : Found in small vugs of coarse quartz with no other associated minerals. On other specimens of schneebergite–nickelschneebergite, the associated minerals are: Co- or Ni-bearing ferrilotharmeyerite, cobaltlotharmeyerite, nickellotharmeyerite, preisingerite, waylandite and zeunerite.

... of this there is a broad absorption ranging from ~3500 cm −1 to 2500 cm −1 with a maximum at 3100 cm −1 indicating strong to very strong hydrogen bonds. Multiple bonds beyond ~1000 cm −1 are from the arsenate groups. The spectrum of zincgartrellite is similar to that of tsumcorite, ferrilotharmeyerite, and gartrellite...
