schmitti in spring and especially in summer may indicate a seasonal migration, occurring together with the transport of the biodetritus and plants fragments over the substrata, as a consequence of the intrusion of the SACW.
On the other hand, biodetritus tend to accumulate in the bottom sediments whereas biosorption is one of the techniques to remove the heavy metals from the water.
Apart from poorly preserved planktonic foraminifera and some sponge spicules, no biodetritus has been found in this section.
The upper part of this formation contains more biodetritus and intraclasts that include angular fragments of corals, molluscs, echinoids, ooids and an abundant ammonite assemblage referred to in Ramalho (1971).
