of odd stars with abundances quite unlike the rest. The abundances deduced from the absorption and emission lines of theinterstellar mediumdo not agree so well, principally in that there is an apparent shortage of refractory elements such as iron. It is likely that these elements are present, ...
The rare earth pattern in sedimentary rocks is nearly constant and is considered to represent the relative abundances of these elements in the continental crust. This pattern is derived principally from mixing of basic and acidic igneous rock patterns. Preliminary calculations indicate that approximately...
A comprehensive study on rare earth elements and yttrium (REY) in vitrain may provide insights into the REY affinity. In this study, abundance and distribution pattern of REY in bulk coal, vitrain band and HCl-HF demineralized vitrain band was investigated. The coal studied in the present ...

This element was discovered by the English chemist Sir William Crookes in 1861 whereas metallic thallium was obtained by the French scientist Claude-Auguste Lamy in 1862. Fig. 1 Position of thallium in the periodic table of the elements Full size image According to Goldschmidt’s geochemical ...
Their production requires a very short and intense burst of neutrons (rapid neutron capture or r-process)1–3. The nuclides are formed via successive neutron captures on seed elements, following a path in the very neutron-rich region of nuclei. However, the relevant astrophysical sites, with ...

Luna 20 soil is remarkably similar to Apollo 16 soil, in its content of 17 mainly volatile or siderophile elements: Ag, Au, Bi, Br, Cd, Cs, Ge, In, Ir, Rb, Re, Sb, Se, Te, Tl, U, and Zn. Like other highland soils, it seems to contain an ancient meteoritic component of frac...
