Sedimentation rates in the Corumbataí River basin, Brazil, derived from 210Pb measurements
(2005-04-25)
Activity profiles of excess 210Pb measured in four sediment cores from the Corumbataí River basin, São Paulo State, Brazil, provided an opportunity to evaluate sedimentation rates that are helpful for defining appropriate ...
Applicability of the 210Pb dating method to quartz-sandstone stalactites
(2022-01-01)
This paper describes the first application of the 210Pb dating method to quartz-sandstone stalactites, which until now had only been used to determine the growth rates of recent carbonate speleothems. Five stalactites were ...
Sedimentation rates in Atibaia River basin, São Paulo State, Brazil, using Pb-210 as geochronometer
(Pergamon-Elsevier B.V. Ltd, 2014)
Pb-210 and compositional data of sediments from Rondonian lakes, Madeira River basin, Brazil
(Elsevier B.V., 2015-05-01)
Gold exploration has been intensive in Brazilian Amazon over the last 40 years, where the use of mercury as an amalgam has caused abnormal Hg concentrations in water bodies. Special attention has been directed to Madeira ...
A comparative evaluation of the CF:CS and CRS models in Pb-210 chronological studies applied to hydrographic basins in Brazil
(Elsevier B.V., 2014-09-01)
The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported/excess Pb-210 models have been applied to a Pb-210 data set providing of eighteen sediments profiles sampled at four riverine ...
The constant flux and constant sedimentation (CF:CS) 210Pb chronological method applied to determine sedimentation rates at Amazon River watershed, Brazil
(2022-03-01)
Activity profiles of excess 210Pb determined in three sediment cores from Amazon River mouth, Amapá State, Brazil, provide the evaluation of sedimentation rates, contributing to a better knowledge of the hydrological ...
