Figure 11

Typical XRPD patterns of representative scale samples (G-03: thick white scale, B1 zone; G-26 and G-27: thin dark brown scales formed inside pumps). Numbers in brackets at the peaks refer Miller indices. Orange lines indicate the diagnostic peaks of aragonite [44]. Note: aragonite (or another mineral phase) was not detected in the studied samples.
