Crystal structure of the uranyl arsenate mineral hügelite, Pb2(UO2)3O2(AsO4)2(H2O)5, revisited: a correct unit cell, twinning and hydrogen bonding

Autor: Pavel Škácha, Václav Petříček, Jakub Plášil

Publikováno v: Acta Crystallographica Section B, Structural Science, Crystal Engineering and Materials

The crystal structure of the uranyl arsenate mineral hügelite is affected by twinning due to reticular merohedry (diffraction type II). This study documents, apart from the correct description of the unit cell and the nature of the twinning, the pos

A survey of hybrid twins in non-silicate minerals

Autor: Giovanni Ferraris, Massimo Nespolo

Publikováno v: European Journal of Mineralogy
European Journal of Mineralogy, Copernicus, 2009, 21 (4), pp.673-690. ⟨10.1127/0935-1221/2009/0021-1937⟩

This article is the second part of the survey presenting a systematic crystallographic analysis of hybrid twins in minerals. Here we deal with silicate minerals and in particular the hybrid twins of allanite, augite, axinite, beryl, chloritoid, clino

An algorithm is presented to derive the twin laws in non-merohedric twins through the systematic search for quasi-perpendicular lattice planes/directions. The twin lattice, i.e. the sublattice common to the whole crystalline edifice built by the twin
