【 摘 要 】

Behavior of mercuryin soil profiles with archaeological black earth (ABE) and surroundings area(SA) from Sítio Ilha de Terra, Caxiuanã, can provide informationon anthropogenic activity of the Amazonian habitat. The samples of ABE and SAsoil profiles were submitted to mineralogical chemical (total and sequential)analysis. The data show that the Hg occurs mainly in goethite and kaolinitein the two soil profiles. The highest concentrations of Hg and Fe are observedin the SA profile. These results indicate that the prehistoric human occupationcontributed to the decrease of the concentration of Hg in soil ABE from Caxiuanã.
