The concentrations of the rare earth elements (REEs) in samples from 15 rivers, from 6 estuarine transects, and of 5 coastal seawaters are reported and have been used with literature data to examine the continuity in average REE pattern between average continental crust and the dissolved input ...
The rare earth elements (REE), particle-size distribution and mineralogical composition in the <2 μm clay fraction from the soils on the floodplains developed by the three major rivers of the Brahmaputra, Meghna and Ganges in Bangladesh were analyzed. REE as the chondrite-normalized curve or ...

Rare earth elements in soil and plant systems - A review The rare earth elements (REEs) form a chemically uniform group and include yttrium (Y), lanthanum (La) and the lanthanides cerium (Ce), praseodymium (Pr), ... G Tyler - 《Plant & Soil》 被引量: 718发表: 2004年 Speciation of...
The depth distributions of La, Ce, Nd, Sm, Eu, Gd, Dy, Er and Yb in the oceanic water column are used to evaluate the marine geochemical cycle of the rare earth elements and their application as water-mass tracers. Access options ...
Abundances of the rare-earth elements (REE) in nine pelagic sediments from the Pacific Ocean floor were determined. Gross features of the REE patterns for the studied samples are similar to those of the North American shale composite (HASKIN , 1966), but rather small but clear differences from...
