Tectonic vs. anomalous magnetic fabrics in sedimentary rocks: a case study from Barrandian, Czech Republic

Popis výsledku v původním jazyce

The study was focused on Ordovician sedimentary rocks and their anisotropy of magnetic susceptibility (AMS). The area under study is situated in the Prague Synform, Bohemian Massif, Czech Republic. Sedimentation in the basin began by Ordovician transgression and continued with siliciclastic rocks to Lower Silurian. The Upper Silurian is typical by carbonatic rocks as well as Devonian. The Silurian and Devonian sedimentary rocks are intensely folded and thrusted, while the Ordovician-rock deformation isnot visible. The aim of the study was to find out whether the Ordovician rocks are actually un-deformed or were affected by strain by using AMS. Over 1500 samples were taken from 55 sites throughout dozen Ordovician formations. Temperature dependence ofmagnetic susceptibility was measured on the samples as well as AMS, which was compared to structural analysis of individual localities. In some specific cases, x-ray analysis or microscopic studies were done.
