The present work is an attempt to establish the stable isotope database for Mesozoic to Tertiary coals from the Pannonian Basin, Hungary. Maceral composition, proximate analysis, sulphur form, sulphur isotopes (organic and pyritic), and carbon isotopes were determined. This database supports the ass
Nitrogen isotopes have played an important part in the acceptance of the hypothesis that SNC meteorites derive from Mars. As a result, these meteorites can be investigated for their carbon, sulphur, and hydrogen systematics with a view to learning something about the environmental conditions on the
Europium has two stable isotopes, Eu 151 and Eu 153. The high isotope shift and the different hyperfine splitting of the energy levels of the two isotopes make it possible to study the isotope ratio by an analysis of the spectral line profiles. From five spectral lines the solar isotope ratio is fou
