    Stratigraphic variation of complex impurities in platform limestones and possible significance of atmospheric dust: a study with emphasis on gamma-ray spectrometry and magnetic susceptibility outcrop logging (Eifelian-Frasnian, Moravia, Czech Rep.)

  • Original language description

    Mineral dust and other constituents of Devonian atmospheric aerosols together with certain amounts of aquatic suspensions of riverine detrital origin, colloidal particle dispersions and seawater solutes were embedded in ~95?98% (or purer) limestones on aconsistently subsiding isolated carbonate platform where they formed very complex impurity systems. The combined method of natural gamma-ray spectrometric and magnetic susceptibility measurements (GRS?MS) together with background of major and trace element analyses provided first systematic insights into fine-scale variability of these impurities in a pile of pure carbonate platform beds, mostly in inner platform Amphipora limestone facies. A long composite stratigraphic section of the Moravian Karst ranges from mid-Eifelian to end-Frasnian levels and yields a number of time characterizing GRS?MS variations that can potentially serve as templates for high-resolution stratigraphic correlations over long distances.

    Změny komplexních nečistot platformních vápenců v čase a pravděpodobný význam atmosférického prachu: studie s důrazem na gamaspektrometrická a magnetosusceptibilitní měření z odkryvů (eifel-frasn, Morava, Česká rep.).

  • Czech description

    Minerální prach a další pevné složky devonského atmosférického aerosolu byly v podobě detritu nebo koloidních částic i roztoků v určitém množství deponovány také do akvatických sedimentárních prostředí, kde byly později zabudovány do relativně čistých karbonátových sedimentů. Kombinace metod gamaspektrometrické analýzy, magnetické susceptibility a analýzy stopových prvků umožnila první systematický pohled na tuto problematiku.
