Study of the ground-state properties of Kr, Sr and Zr isotopes has been performed in the framework of the relativistic mean field (RMF) theory using the recently proposed relativistic parameter set NL-SH. It is shown that the RMF theory provides an unified and excellent description of the binding energies, isotope shifts and deformation properties of nuclei over a large range of isospin in the ...

The Lonar impact crater in the Deccan Traps of the Indian peninsula provides unique opportunities to study physical and chemical processes of impact cratering on basaltic targets, because terrestrial impact craters on basalts are extremely rare. Such studies are needed for determining provenance and other parameters of the excavated rocks and the cratering phenomenon that may have implications ...

Despite the recent discovery of superconductivity in Nd$_{1-x}$Sr$_{x}$NiO$_2$ thin films, absence and antiferromagnetism their bulk materials remain a puzzle. Here we report $^{1}$H NMR measurements on powdered Nd$_{0.85}$Sr$_{0.15}$NiO$_2$ samples by taking advantage enriched proton concentration after hydrogen annealing. We find large full width at half maximum spectrum, which keeps increasi...

Introduction: Metadolerite dykes in the Western Dharwar Craton represent oldest generation of mafic dyke swarms craton. The emplacement these after a period crust building activity and komatiite volcanism, helps to understand evolution Subcontinental Lithospheric Mantle (SCLM) Archean dynamics. Methods: We report whole rock major, trace element geochemistry Sr-Nd isotope characteristics for thi...

The origins of Cenozoic granites in the Himalaya are key to understanding evolution Himalayan orogen. However, it is unclear whether these represent primary melts, and nature their magma source controversial. Here, we present a systematic element Sr–Nd–B–Mo isotope study from Yardoi area eastern Tethyan Himalaya, China. These can be divided into two groups: mid-Eocene porphyritic two-mica with ...

Neoproterozoic gneisses at Meatiq and Hafafit in the Eastern Desert of Egypt give Rb–Sr and U–Pb zircon ages of 600–750 Ma. These gneisses are interpreted by different workers to represent deeper levels of juvenile Neoproterozoic crust or Archaean/Palaeoproterozoic crust that was remobilized during Neoproterozoic time. Geochemical and Sr–Nd isotope compositions for these gneisses reported here ...

Abstract Anatolia is characterised by a complex geodynamic evolution, mirrored wide spectrum of magmatism. Here, we investigated the timing and geochemical/isotopic characters Miocene to Pliocene volcanism Sivas–Malatya Region (Central Eastern Anatolia), its relationships with local regional tectonics. Na-alkaline basaltic lavas were emplaced during middle at Sivas (16.7–13.1 Ma), in North, whi...
