Sedimentation rates in the Corumbatai River basin, Brazil, derived from Pb-210 measurements
(Int Assoc Hydrological Sciences, 2005-01-01)
Activity profiles of excess Pb-210 measured in four sediment cores from the Corumbatai River basin, São Paulo State, Brazil, provided an opportunity to evaluate sedimentation rates that are helpful for defining appropriate ...

A 210Pb chronological study in sediments from poços de caldas alkaline massif (PCAM), Brazil
(2018-07-01)
The Constant Flux and Constant Sedimentation (CF:CS) of supported/excess 210Pb model was successfully used to study sediment profiles from Antas stream, located in the region of Poços de Caldas city, Minas Gerais State, ...

Effect of PbO excess on the formation of lead magnesium niobate perovskite by the columbite method
(Elsevier B.V., 2004-03-15)
The effect of lead excess on the pyrochlore-type formation in Pb(Mg1/3Nb2/3)O-3 (PMN) powders has been investigated. The polymeric precursor method was used in the synthesis of the columbite in association to the partial ...

Sedimentation rates in Atibaia River basin, São Paulo State, Brazil, using Pb-210 as geochronometer
(Pergamon-Elsevier B.V. Ltd, 2011-01-01)
The constant initial concentration (CIC) of unsupported/excess Pb-210 model was successfully used to assess Pb-210 data of nine sediment cores from Atibaia River basin São Paulo State Brazil The Pb-210-based apparent ...
Identifying sedimentation processes in the Coata River, Altiplano of the Puno department, Peru, by the 210Pb method
(2019-11-01)
The rivers, lakes and dam sediment analyses are able to predict the back conditions of these ecosystems and determine how the environment changed as a result of anthropogenic activities. In this way they can be used as ...
