Resumo
The goal of the present work was to determine the concentration of 21 elements by instrumental
neutron activation analysis (INAA) and subsequent gamma spectrometry, in order to investigate the
contribution of the local lithology of the Itinguçú River Basin Drenage, that ends in a mangrove area
not yet largely impacted by others sources such as industrial and domestic waste. So far there is no
available data for trace elements of the lithology and this data is important to the understanding of
the contribution of the rocks to the mangrove sediments. The results showed some enrichment of Th
and some light rare earth. This is probably due to the presence of allanita, a mineral found by
petrographic analysis.
