Caracterização litológica do furo de sondagem FDN 17-01 do depósito de manganês da região da serra do sereno, Curionópolis, Sudoeste do Pará

Abstract

The Manganese deposit of Serra do Sereno is located in the municipality of Curionópolis, near to Vila Alto Bonito, approximately 160 km from Marabá, in the south direction. It is inserted in the geological context of the Carajás Province, eastern portion of the Amazonian Craton. The deposit is hosted by hydrothermally altered metasedimentary rocks of the Grupo Rio Novo, of neoarquean age, in which chlorite schists, sericite schists, graphite schists and quartzites occur. Due to the few published scientific papers in relation to the local geology, references of the region of the Sereno are usually found correlated to the manganese deposits of Buritirama, fact that impelled this paper to realize a more in depth study about the geology of the region. To do so, as a result of the availability of a drilling hole (FDN 17-01) by the RMB Manganês enterprise, a macroscopic characterization of the rocks was carried out as well as analyzes by X-ray diffraction and X-ray fluorescence spectrometry by dispersive energy, in order to contribute with new information on this important mineral deposit.
