Figure 21
Segregation of main cations (Pb, Sb, As) along the mono-atomic ribbons (colored segments) in the structure of parasterryite according to their x coordinate. The dotted lines separate adjacent zigzag layers according to an a/4 shift relative to the structure of sterryite, explaining the distinct cell settings of sterryite and parasterryite (see the distribution of the green and red triangles (symbols of the axes of the columns) between this figure and Fig. 19[link]).
