Contamination in the Rare-Earth Element Orthophosphate Reference Samples
Several of the fourteen rare-earth element (plus Sc and Y) orthophosphate standards grown at Oak Ridge National Laboratory in the 1980s and widely distributed by the Smithsonian Institution's Department of Mineral Sciences, are significantly contaminated by Pb. The origin of this impurity is the Pb2P2O7 flux that is derived from the thermal decomposition of PbHPO4. The lead pyrophosphate flux i...
متن کاملA Re-examination of the Rare-earth-element Orthophosphate Standards in Use for Electron-microprobe Analysis
A re-examination of fourteen standards consisting of orthophosphates of the rare-earth elements, Sc and Y, grown at Oak Ridge National Laboratory in the 1980s and widely distributed by the Smithsonian Institution’s Department of Mineral Sciences, reveals that some of the material is significantly contaminated by Pb. The origin of this impurity is the Pb2P2O7 flux that is derived from the therma...
متن کاملRare earth element geochemistry of outcrop and core samples from the Marcellus Shale
In this work, the geochemistry of the rare earth elements (REE) was studied in eleven outcrop samples and six, depth-interval samples of a core from the Marcellus Shale. The REE are classically applied analytes for investigating depositional environments and inferring geochemical processes, making them of interest as potential, naturally occurring indicators of fluid sources as well as indicato...
متن کاملOverland Flow Using Rare Earth Element
14 15 Rare earth element oxides (REOs) have excellent potential for use as tracers in 16 erosion studies. Using laboratory and field experiments we aimed to develop and test 17 a simple application method for spreading REOs and to use REOs to determine the 18 source of sediment to concentrated overland flow paths. 19 Tracks left by farm machinery (tramlines) in fields act as concentrated flow 2...
