Dear Luca,
I think ice is not claimed to be turbostratic (see PNAS paper). I think
the disorder in cubic ice case is much closer to the the planar disorder
you can experience in close-packed metals (or in SiC, Laves phases, etc)
than to clays.
Best regards

: Stacking faults and antiphase boundary
Dear all,
I think Jon is right. In the case of Cu this is the position of a (100)
reflection of a hcp polytype. I have seen this feature in a couple of
cases, and presence of this feature is sometimes taken as a sign for a
two-phase character of the specimen
Glad the discussion is opening a bit.
Actually the Ice case is a bit different from the point of view of the
defects. These are turbostratic planar defects (in the case of close
packed alloys you have twins and intrinsic and extrinsic deformation
faults). Now it is true that there is not a big dif
