Relative abundances of rare earth elements (REE) in geological materials are used widely to investigate diverse geochemical issues such as the origins of igneous rocks or the degree of stratification of water columns in ...
X-ray-absorption near-edge structure (XANES) was successfully applied for the direct determination of Ce valence in hydrogenetic ferromanganese nodules (two samples) and crust (one sample). Rare earth element (REE) patterns ...
