摘要：
Geochemical and mineralogical characteristics of the mangrove sediments are inherited from source areas, continental and marine, through the contribution of particulate or ionic material brought by the currents. The objective of this study was geochemically to characterize the sediment of a mangrove forest in north estern Para State (Brazil). The sediment showed a predominance of finer fraction (58% silt and clay) and high concentrations of minerals SiO( )and Al2O3. And the elements - trace Pb, Mo, Ga, As, Rb, Cs, Ba, V, Ni, Co, Zn, Cu, Sc and Y showed the typical values found in the region. The mangrove area present chemical characteristics of a site that does not suffer from human disturbance. A more detailed study, taking into account the seasonal factor, would help in observing the behavior of the species.
