原始语种摘要: Abstract(#br)The chemical weathering rate and atmospheric/soil CO 2 consumption of Paraná flood basalts in the Preto Stream basin, São Paulo State, Brazil, were evaluated using major elements as natural tracers. Surface and rain water samples were collected in 2006, and analyses were performed to assess pH, temperature, dissolved oxygen (DO), electrical conductivity (EC) and total dissolved solids (TDS), including SO 4 2− , NO 3 − , PO 4 3− , HCO 3 − , Cl − , SiO 2 , Ca 2+ , Mg 2+ , Na + and K + . Fresh rocks and C horizon samples were also collected, taking into account their geological context, abundance and spatial distribution, to analyze major elements and mineralogy. The Preto Stream, downstream from the city of Ribeirão...
