“…This component might be related to a recent viscous magnetic overprint, also considering that the Meso-Cenozoic sediments of the Umbria-Marche basin are commonly characterized by a similar lowtemperature component falling close to the GAD field direction (e.g. Channell et al, 1982;Lanci et al, 1996;Turtù et al, 2013;Satolli et al, 2015;Satolli and Turtù, 2016). The remaining 30 samples exhibit a low-temperature component, also removed around 150 °C, with reverse polarity probably indicating a viscous overprint of a different origin or acquired earlier than the rest of the samples.…”

“…The long normal N2 interval must be interpreted as the M19n2n. The boundary between Crassicollaria and Calpionella zones is usually situated within this magnetozone (for review, see Ogg et al 1991;Grabowski 2011;Satolli et al 2015). The short R2 and N3 intervals, in the lower part of the Alpina Subzone, are respectively correlated with the M19n1r ("Brodno") and M19n1n magnetosubzones.…”

Abstract:A well preserved Upper Tithonian-Lower Berriasian Strapkova sequence of hemipelagic limestones improves our understanding of environmental changes occurring at the Jurassic/Cretaceous boundary in the Western Carpathians. Three dinoflagellate and four calpionellid zones have been recognized in the section. The onset of the Alpina Subzone of the standard Calpionella Zone, used as a marker of the Jurassic/Cretaceous boundary is defined by morphological change of Calpionella alpina tests. Calpionellids and calcified radiolarians numerically dominate in microplankton assemblages. The first occurrence of Nannoconus wintereri indicates the beginning of the nannofossil zone NJT 17b Subzone. The FO of Nannoconus steinmannii minor was documented in the lowermost part of the Alpina Subzone. This co-occurrence of calpionellid and nannoplankton events along the J/K boundary transition is typical of other Tethyan sections. Correlation of calcareous microplankton, of stable isotopes (C, O), and TOC/CaCO 3 data distribution was used in the characterization of the J/K boundary interval. δ 13 C values (from +1.09 to 1.44 ‰ VPDB) do not show any temporal trends and thus show a relatively balanced carbon-cycle regime in sea water across the Jurassic/ Cretaceous boundary. The presence of radiolarian laminites, interpreted as contourites, and relatively high levels of bioturbation in the Berriasian prove oxygenation events of bottom waters. The lower part of the Crassicolaria Zone (up to the middle part of the Intermedia Subzone) correlates with the M19r magnetozone. The M19n magnetozone includes not only the upper part of the Crassicollaria Zone and lower part of the Alpina Subzone but also the FO of Nannoconus wintereri and Nannoconus steinmannii minor. The reverse Brodno magnetosubzone (M19n1r) was identified in the uppermost part of M19n. The top of M18r and M18n magnetozones are located in the upper part of the Alpina Subzone and in the middle part of the Ferasini Subzone, respectively. The Ferasini/Elliptica subzonal boundary is located in the lowermost part of the M17r magnetozone. A little bit higher in the M17r magnetozone the FO of Nannoconus steinman nii steinmannii was identified.
