Figure 1
Part of the measured high-resolution X-ray diffraction spectrum of powdered geological aragonite (open circles) superimposed on the best-fit calculated Rietveld refinement profile (solid line) and their difference (solid line at the bottom). Upper, middle and lower rows of tick marks represent Bragg positions of aragonite, α-quartz and calcite reflections, respectively. The insert shows two closely related diffraction peaks, 200 (on the right) and 102 (on the left), the latter missing in the JCPDS file 41–1475. |
