Zippeite from Cap Garonne, France: an example of reticular twinning
Original language description
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).
