Pictures of the  oncoid beds. Kershaw et al. (1999) argued that these may have been formed in maximum of 65 m water depth, based on modern oncoids.


Here the oncoids are recrystallised and microbialite sructures are not visible.


Vertical section photos of polished slices.








Lower photos are vertical thin sections of oncoids. Bottom photo has a shell.
