The significance of the δ~(18)O data is minor compared to the study of the mineralogy and crystallography of the various types of NFCs. Lacelle (2010) uses the general term NFC for all of the various crystal habits, whereas we demonstrated that there are different types of NFCs originating from various processes, including possible evaporation, and possibly from different parent solutions (early diagenesis). 收起
