Rare earth element geochemistry in saline alkaline lakes from the East African Rift, Kenya: the case of the “missing” Ce anomaly

Many of the East African Rift Valley lakes are soda lakes that have attracted considerable research interest over the last decades with a focus on their extraordinarily high bioproductivity, high concentration of dissolved organic carbon (DOC), and diverse microbial communities. Yet, the distribution of trace metals, particularly dissolved rare earth elements (REE) and yttrium in these soda lake systems remain poorly constrained. We report data for surface water samples from eight rift valley la
