Photomicrographs under transmitted light showing glauconite pellets in the Pariwar Formation (a, b). Glauconite pellets (c) and infillings (d) in the Habur Formation (c, d). SEM images showing the rosette texture (e) in the Pariwar Formation and lamellar texture in the Habur Formation (f). X-Ray mapping showing compositional variation (g-l). Ca-enrichment indicates part indicates bioclast test (h), while simultaneous enrichment in Al, Fe, K, and Si indicates glauconite infilling within the chambers (i-l).
