- W2051691750 abstract "TIMS analysis of the 234U/238U radioactive disequilibrium in river and spring waters of the Mt Cameroon volcano has been undertaken (1) to constrain the parameters controlling the supply of U isotopes to freshwaters, and (2) to evaluate the potential interest of the U activity ratio in dissolved loads of river waters as a tracer of rock weathering. The MountCameroon volcano has the advantage to provide a wide but nearly monolithological geographical area, which consists essentially of alkali basalts and to present an intense tropical weathering at different evolution stages depending on the age of the successive volcanic flows. Thirty six river and spring waters draining and flowing over the Mount Cameroon volcano were collected during two campaigns in December 1996 and May 1997. These samples were filtered on site at 0.1~tm, and splited in different aliquots used for analysis of the major and trace elements, and the oxygen, Sr and U isotope compositions. In twelve sampling sites, about 40L of water were also treated by ultrafiltration techniques using Sartorius ultrafiltration cartridges with successive cut-off at 0.22gin, 100kDalton (~0.02~un) and 5kDalton (~0.002gin). For each ultrafiltration experiment, the ultrafiltrates and the colloid concentrates were collected and treated for chemical and isotope analysis. Results obtained for the (234U/238U) ratio and the U, Rb and Sr concentrations are presented here. The (234U/238U) isotope ratios were measured with a precision of 0.5% (2c~ error) on a VG sector mass spectrometer. The concentrations of U, Rb and Sr were determined by an ICP-MS Fisons VGPlasmaQuad with a detection limit of 0.01mg/L.
