Acesso em: 24 de set. 2014.0375-6742http://www.repositorio.ufop.br/handle/123456789/3799This paper investigates the denudation rates in the Quadrila´tero Ferrı´fero, Minas Gerais State (Brazil). The aim is to compare chemical weathering rates from measurements of solute fluxes in rivers and long-term mean erosion rates deduced from in situproduced cosmogenic 10Be concentrations measured in fluvial sediments. Both water samples and sediments were collected in fifteen stations (checkpoints) located in four hydrographic basins with low anthropogenic perturbations. Depending of the type of substratum, three degrees of chemical denudation rates from water samples are observed: (i) high rates in marbles; (ii) medium rates in schists, phyllites, granites, gneisses and migmatites; (iii) low rates in quartzites and itabirites. Preliminary results of long-term erosion rates deduced from in situ-produced 10Be are comparable with those of chemical rates.en-USWeatheringDenudationCosmogenic nuclidesQuadrilátero FerríferoArtigo publicado em periodicoO periódico Journal of Geochemical Exploration concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
