Figure 3
Diopside-(Fe). (a) Cross-polarized photomicrograph of one of the studied crystals (black) interpenetrated by the finely grained matrix. The crystal edges are approximately 1 mm long. The size of the beam focus (15 × 15 µm) allows analysis of a homogeneous part of the crystal. (b) Model-free whole-pattern refinement, showing the observed pattern (dots), the calculated pattern (line) and their difference (bottom). The observed pattern corresponds to the circular average of the sum of collected two-dimensional patterns.
