The impact of vegetation on REE fractionation in stream waters of a small forested catchment ( the Strengbach case )
International audience Previous studies on waters of a streamlet in the Vosges Mountains (Eastern France) have shown that strontium and rare earth elements (REE) mainly originate from preferential dissolution of apatite during weathering. However, stream water REE patterns normalized to apatite are...
