Thin section illustrations characterizing the microfabrics of the microbial and metazoan buildups (see Fig. 9 for description and classification and Figs. 6, 7 and 9 for position). A. Cross-section of the caddisfly pupal cases trapping ooids (Oo) and encrusted by Broutinella avernensis (Jus-64). B. Cross-section of the caddisfly pupal cases (Cpc) trapping gastropod shells encrusted by microbialites (Gs; Cre-36A). C. Microbialites developed upon clastic sands showing very low trapping of quartz during microbial growth (Jus-61); Cavity are infilled by a brown micrite (bMi) and ostracods (Ost). D. Coalescent oncoids embedded in clastic sands and trapping grains (Jus-61). E. Transition from cluster of Cladophorites to microbialites showing an alternance of cement and micritic layers (Jus-48A). F. Microbialites showing an alternance of laminated cement and micritic microfabrics (Jus-53A). G. Successive layers composed of filaments (Fi) embedded in micrite and microsparite (Ch-21). H. Dark micrite-dominated laminae stacked to form column (Col) and dense filament-rich layers (Fi; Ch-5).
