    U–Pb Age and Geochemistry of Detrital Zircons from Quartzites of the Daldyn Group, Anabar Shield, Northern Central Siberia, Russia

    The paper presents U–Pb zircon dates (SHRIMP-II) and isotopic-geochemical data (SIMS and Sm–Nd method) on detrital zircon and its sedimentary host rocks of the Daldyn Group at the Anabar Shield. The rocks were...

    Relics of the Eoarchean Continental Crust of the Anabar Shield, Siberian Craton

    In the northern part of the Anabar Shield, orthopyroxene plagiogneisses of the granulite Daldyn Group host lenses of mafic rocks surrounded by melanocratic rims. According to their chemical composition, the ma...

    Age and origin of rocks of the Daldyn Group of the Anabar Shield: Evidence from U-Pb zircon dating, Sm-Nd and Lu-Hf isotope systematics

    The Hf-Nd isotope systematics was used to determine the genesis of zircons from granulites of the Daldyn Group of the Anabar Shield. Obtained age of magmatic crystallization for biotite–hypersthene crystalline...

    A model study of vibrational excitation of carbon dioxide molecule by slow electrons: the role of wave packet sliding from the ridge

    The method of an accurate calculation of vibrational excitation cross sections of a two-mode molecule by slow electrons within the framework of the local theory (the ‘boomerang’ model) is applied for a model s...

    Theoretical premises for experimental verification of the deviations from the wannier threshold behaviour

    The Wannier [1] theory describes the escape of two electrons from a charged core in the threshold domain. Its modification [3] is applied to some features of the double escape processes which were not analyzed...
