“…This reasoning is also coherent if part of these brines originates from the dissolution of evaporites. Indeed, waters draining evaporites present usually very high ( 234 U/ 238 U) values (Riotte et al, 1999;Durand et al, 2005;Lucas et al, 2010).…”

“…As a consequence, groundwater usually presents higher ( 234 U/ 238 U) values than river water (e.g., compilation in Chabaux et al, 2008). Therefore, ( 234 U/ 238 U) ratio was used to trace and quantify the contribution of more or less deep groundwater to river waters (Riotte and Chabaux, 1999;Durand et al, 2005). Based on these studies, we propose that high ( 234 U/ 238 U) values measured in winter waters reveal a deep origin of element fluxes carried by Kochechum and Nizhnyaya Tunguska rivers at this period, and a much shallower origin of chemical flux during spring and summer floods.…”

“…This study is based on the geochemical tracing approach that combines analyses of major and trace element concentrations with analyses of Sr and U isotopic ratios; indeed, these multi-method approaches have been shown to be a powerful tool for deciphering the source of elements in river water (Négrel et al, 1993;Cameron et al, 1995;Gaillardet et al, 1999;Riotte and Chabaux, 1999;Dupré et al, 1999;Jacobson et al, 2003;Durand et al, 2005;Derry et al, 2006;Pogge von Strandmann et al, 2006;Viers et al, 2000Viers et al, , 2008. The main questions addressed here are how the annual variations of major and trace element concentrations and Sr and U radiogenic isotopes are linked to the hydrological regime and to which extend these parameters can be used to trace the sources of elements and their migration pathways through continuous permafrost terrain.…”

“…Groundwaters can be another source of uranium to rivers, the insignificance, however, would depend on their contribution to water discharge and their uranium concentration (Durand et al, 2005). In the samples analysed in this study, the Chambal was sampled during the tail end of monsoon when river stage was high and the Yamuna during post-monsoon when water flow is medium to high.…”

Dissolved uranium concentration and 234 U/ 238 U activity ratio have been measured in two distinctly different Indian drainage systems: the Yamuna headwaters in the Himalaya and the Chambal river system in the plains to study the weathering and mobility of uranium in these watersheds. The dissolved uranium in the Chambal river system ranges from 0.2 to 1.74 lg L )1 during September (tail end of monsoon), whereas in the Yamuna river system, its concentration varies from 0.1 to 3.18 lg L )1 during October (post-monsoon) and from 0.09 to 3.61 lg L )1 in June (summer). In the Yamuna main stream, uranium is highest at its source and decreases steadily along its course, from 3.18 lg L )1 at Hanuman Chatti to 0.67 lg L )1 at Batamandi, at the base of the Himalaya. This decrease results mainly from mixing of the Yamuna mainstream with its tributaries, which are lower in uranium. The high concentration of uranium at Hanuman Chatti is derived from weathering of the Higher Himalayan Crystalline series (HHC) and associated accessary minerals, which may include uranium-mineralised zones. The 234 U/ 238 U activity ratios in the samples from the Chambal watershed are in the range of 1.15±0.05 to 1.67±0.04; whereas in the Yamuna the ratios vary from 0.95±0.03 to 1.56±0.07, during postmonsoon and from 0.98±0.01 to 1.30±0.03, during summer. The relatively high 234 U/ 238 U activity ratios in the Yamuna system are in its tributaries from the lower reaches viz., the Amlawa, Aglar, Bata, Tons and the Giri. It is estimated that $9Â10 3 and $12 Â 10 3 kg of dissolved uranium are transported annually from the Yamuna at Batamandi and the Chambal at Udi, respectively. This corresponds to uranium weathering rates of 0.9 and 0.09 kg U km )2 y )1 in the basins of the Yamuna and the Chambal headwaters. This study confirms that uranium weathering rate in the Himalaya is far in excess (by about an order of magnitude) of the global average value of $0.08 kg U km )2 y )1 .
