Figure 5

Raman image of mixed calcium oxalate and apatite stone fragment. Mapping was performed with 1 µm spatial resolution. Region (A) shows mixed apatite originating from in vivo growth and calcium carbonate that formed from laser damage during prior Raman analysis. Region (B) shows COM plates growing from COD dissolution. Region (C) shows an example of a large COM hexagonal plate. Region (D) Large COM crystal with apparent layering of organic matter. Maps for individual mineral components are shown in Figure S12.
