Rare earth elementsLanthanidesYttriumNorth-West RussiaParent materialsArable soilsThis study presents the rare earth elements (REE) and Y concentrations in the main soil forming materials and ploughing horizons of North-West Russia agricultural soils. The study area covers Leningrad region, west part of...
This study examines the rare earth elements and yttrium(REY) concentrations of twenty-five samples from the reef outcrop exposed along the Lianglitage Mountain in the Ordovician, Tarim Basin in China. The concentration analysis provides constraints on the paleoenvironment during reef deposition. Based ...

Rare earth elements and yttrium (REY) in coal, or REE if Y is not included, have attracted an increasing interest in recent years [1], [2], [3], [4], because of their potential enrichment in coal, associated ash and some of the non-coal bands within the coal bed, as well as th...
Rare earth elements (metals) are the elements scandium (Sc), yttrium (Y), and the lanthanides (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu). These elements got their name from the fact that chemists first isolated them in their oxide forms
Related to rare-earth element:noble metal (râr′ûrth′) n. Any of a group of 17 naturally occurring metallic elements that have similar properties, consisting of scandium, yttrium, and the 15 elements with atomic numbers 57 through 71 (the lanthanides). The rare-earth elements are widely...
The impact of burial diagenesis(especially deep burial-related processes such as thermochemical sulfate reduction,TSR) on the distribution of rare earth elements and yttrium(REY) in diagenetic minerals in carbonate reservoir has gained little attention even though they may be unique indicators of the ...
