Figure 3

WDS spectra of different foraminiferal (Alveolina, Discocyclina, Nummulites, Planktic) and invertebrate macrofossils (bivalve, brachiopod and gastropod) obtained through EPMA analysis. Fe and Al are absent in planktic foraminifera, whereas merely present in gastropod and bivalve. Enrichment of Fe and Al is observed within the surficial part of Alveolina, Discocyclina, Nummulites, and brachiopod.
