... with cortoids and oncoids characterize open-marine intervals. Laminoid-fenestral mudstones and wackestones with oncoids were common in restricted-marine intervals. Fusulinids and algal and peloidal grainstones are common marginal-marine facies. Restricted-marine sediments were deposited after clastic influxes...

.... These fenestral/peloidal networks are about 1–3 mm thick, and display varied amoeboid, lump-shaped as well as laminoid forms; features which also resemble the spicule and deteriorated spicule networks in zone 1 ( Fig. 8 B– 8 F). Peloids, located in both fenestral and peloidal networks often ‘float' in the blocky...
