"Basal Chote\u010D Event (close the Lower-Middle Devonian boundary, Prague Synform) has distinct correlatable magnetic susceptibility (MS), gamma spectrometric (GRS), and geochemical patterns. The MS record produces a smooth curve below the \uFB01rst event-related beds and a rapid increase in MS values with oscillations above. The GRS record shows a reversal in the Th to U ratio at the event base from values above 1 to below 1. REE distributions show very uniform patterns indicative of their aeolian origin. A similar trend is displayed both in the deeper- and shallow-water environments. Light and heavy mineral assemblages are dominated by dia-, paramagnetic (kaolinite, chlorite, pyroxene/amphiboles, apatite, barite, feldspars, muscovite) and ferromagnetic minerals(Fe oxides-oxyhydroxides). The MS and GRS data, together with the lithology(calcisiltic hemipelagic material below the event base and recycled skeletal detritus from turbidite currents above),suggest the sea-level rise at event interval."@en . .
