V originále

Studied area is situated in southern part of the Třebíč Pluton, which is a plutonic body consisting of durbachitic rocks situated in the Bohemian Massif. The pluton intruded into the Variscan orogenic root (Moldanubian Unit) before 335–340 Ma (Kotková et al., 2010). Internal structure of the body was investigated using anisotropy of magnetic susceptibility (AMS), which well reflects magmatic- and strain-originated preferred orientation of magnetic minerals. Over 162 samples were taken using a portable drill at 25 sampling sites covering the area under study. Results of AMS analysis were compared with mesoscopic structural observations (compass data). Essentially, there are four groups with different directions of magnetic foliation. The degree of anisotropy varies from 1.013 to 1.154. The value of degree of anisotropy increases from south to north. The shape parameter T varies from strong prolate (-0.820) to medium oblate (0.510). Vectors K1 show magnetic lineations developed in NW-SE direction and plunging to the NW or N under low angels. Vectors K3 are normals to magnetic foliation, which is steeply dipping mostly to the W. There was also used an analysis of temperature dependence of magnetic susceptibility. This method showed that all fabrics in these rock in southern part of pluton are controlled by paramagnetic minerals such as amphibole and biotite.
