Figure 2
(a) SAED patterns of kaliophilite from Pollena (Vesuvius, Naples, Italy), with zone axis [001]. The reciprocal cell of kaliophilite is sketched in white, whereas the reciprocal vectors corresponding to the 15.6 Å periodicity are represented in gray. In (b) the corresponding HRTEM image is shown. The arrow indicates a slab with apparent 15.6 Å periodicity within the kaliophilite crystal. Other defects are also visible [modified from Bonaccorsi (1988BB10)].
