Name:
Kolitschite is named for Dr Uwe Kolitsch (b. 1966), Curator of Mineralogy at the Natural History Museum, Vienna, Austria, to recognise his contribution to mineralogy — in particular to the characterisation of new minerals (of which he has been involved in ~30) and crystallography, whilst also recognising his work on alunite-group minerals.


Related to minerals of the Dussertite Group (Alunite Supergroup), especially zincian kintoreite and segnitite.

The crystal structure differs from those of other alunite-type minerals in having zinc atoms ordered in trigonal bipyramidal sites in half of the available six-membered rings of the layers of octahedra. These sites are unoccupied in previously reported alunite-type structures. The ordering results in monoclinic symmetry and multiple twinning by 120° rotations about c*.

A solid-solution series extends between Pb[Zn0.25,□0.75]Fe3H(AsO4)2(OH)6 and the endmember Pb[Zn0.5,□0.5]Fe3(AsO4)2(OH)6.
