Abstract (in english)
   Multiple magnetic lineations were revealed using the anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AMR) methods in a domain of mafic-felsic magma mingling at the northwestern margin of the Sazava pluton, Central Bohemian Plutonic Complex, Bohemian Massif

   Multiple magnetic lineations were revealed using the anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AMR) methods in a domain of mafic-felsic magma mingling at the northwestern margin of the Sazava pluton, Central Bohemian Plutonic Complex, Bohemian Massif. Gabbrodioritic enclave swarms and sheets are steeply oriented and exhibit magnetic lineations plunging at steep to moderate angles (mostly 40-70 degrees) whereas in their tonalitic host lineations plunge from vertical to horizontal angles, but mostly less than 40 degrees. The magnetic lineations in both rock types spread along a similar to NNE-SSW steep plane that could be simplified as representing an "average" margin-parallel magmatic foliation in the pluton concordant with an "average" regional cleavage in the wall-rock.
