Anotace

V originále

The work was focused on the Upper Proterozoic metasedimentary rocks, studies of their anisotropy of magnetic susceptibility (AMS). Research was held in Kralupy-Zbraslav and Štěchovice formations that are situated in Barrandian, Czech Republic. There is a 15–20 km wide and about 60 km long stripe among Prague, Dobříš, Přibram, Rožmitál pod Třemšínem and Nový Knín. About 220 oriented samples were collected by manual drilling machine from outcrops or in laboratory from oriented blocks. AMS of drilled cores was measured in AGICO laboratories Brno on MFK1 instrument. In studied rocks were founded two types of AMS fabrics (see Fig. 1). Types are caused by different litology: fine-grained sediments are associated with oblate fabric with dominated magnetic foliation (bedding), however the coarse-grained ones generate prolate fabric indicating strain. Two orientations of AMS fabrics, found on studied area, are presumably called by different deformations. The most common deformation is varisian, AMS axis are oriented NW-SE. This deformation was caused by massive intrusions on NE of region. The second AMS fabric of unknown origin is oriented NE-SW. During our studies was found one site (28) with inverse fabric. This may be caused by ankerite or siderite and need further investigation.
