Example of the detected calcium oxalate in sample 16. On the left (a and b), the known reflections of whewellite (CaC2O2) and weddellite (CaC2O4) were used to construct the scattering data on the selected q-scale (1.0–1.15 Å−1). On the right (c), is the scattering data of sample 16 with the reflections of whewellite and weddellite which shows the crystal contains these compounds
