REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]
, 2001 Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...
