Resumo: | This work investigates the distribution of selected heavy elements in soil samples and Si-Phytoliths from plants. The aim is to verify if metal contents are indicative for metal anomalies in the soil. Samples were collected in profiles near the Riacho dos Machados Goldmine. Granitic-gneissic rocks, in tectonized contact with the overlaying rocks, form the basis of the investigated region, which belongs to the Rio dos Machados Group of the Espinhaço Super Group. The whole rock substrate is covered by lateritic to arenitic soils with different exposure depths. Metal-rich fluid invaded this unit, forming metal anomalies, forming Zn-Pb-Au deposits, like that of Salobre-Porteirinha. After appropriate preparation, the samples were analyzed by ICP-OES (Si-Phytoliths) and XRF (soil). Anomalies in the investigated profile are indicated by high metal contents in the Si-Phytoliths of the selected species. Using different species, the metal concentration at different depths can be determined. |

O objetivo é verificar se os teores de metais são indicativos de anomalias metálicas no solo. As amostras foram coletadas em perfis próximos à Mina Riacho dos Machados. Rochas granítico-gnáissicas, em contato tectonizado com as rochas sobrepostas, formam a base da região investigada, que pertence ao Grupo Rio dos Machados do Super Grupo Espinhaço. Todo o substrato rochoso é coberto por solos lateríticos a areníticos com diferentes profundidades de exposição. Fluido rico em metais invadiu esta unidade, formando anomalias metálicas, formando depósitos de Zn-Pb-Au, como o de Salobre-Porteirinha. Após o devido preparo, as amostras foram analisadas por ICP-OES (Si-Phytoliths) e XRF (solo). Anomalias no perfil investigado são indicadas por altos teores de metais nos Si-Fitólitos das espécies selecionadas. Usando diferentes espécies, a concentração de metal em diferentes profundidades pode ser determinada.engUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASRomanian journal of mineral depositsCerradoPlantasMetaisPossible use of Si-Phytoliths in metal anomaly prospection.
