Abstract/NotesAbstract
We describe here the case of twinning by reticular (pseudo)merohedry in case of natural zippeite crystal from Cap Garonne, France. The twin is by two-fold rotation in [100] and it is a first document of this type of twinning in zippeite-related minerals and compounds. Zippeite crystals from Cap Garonne mine, France, were studied by single-crystal X-ray diffraction [a=8.7243(4), b=13.9337(7), c=8.8741(4) Å, β=104.243(5) and V=1045.59(9) Å3, Z=2, in C2/m]; refinement taking into account of the twinning resulted in R=2.81% for 1596 reflections with [I>3σ(I)] and refined twin fraction 0.7773(9):0.2227(9).
