This work represents the first results of AMS research in Kralupy-Zbraslav and Štěchovice formations. These formations are located in Barrandian from central Bohemia region among Prague, Rožmitál pod Třemšínem and Nový Knín. It is a 15–20 km wide and about 60 km long stripe of slates, siltstones, graywackes, and conglomerates. The belt is oriented in SW-NE direction and main bedding surfaces as well as cleavage planes strike approximately in the same way. Oriented samples were taken by manual drilling machine from outcrops or in laboratory from oriented stones. Cores, 25 mm in diameter and 20-25 mm length, were measured in AGICO laboratories, on MFK1 device. The first sets of samples were studied in five localities, where anisotropy of magnetic susceptibility (AMS) was measured. Orientation of principal directions of AMS is shown in azimuthal plots (see Fig. 1). These pilot results indicate that AMS is not uniform in the area under study, and therefore strain influence was different in different domains. AMS shows expected SW-NE direction of magnetic lineation (K1) on localities S-4 and K-2, which well corresponds to trend of pencil structures found on these localities. Similar fabric (less insensive) seems to be on S-11 site. Another pattern of AMS was found at S-15 site, where perpendicular orientation was recognized (K1 in NW-SE direction). And the last studied locality, S-12 shows very diffuse fabric, which may originated in sdimentary process.
