N2 - Studied area is situated in Brno massif. The metabasite zone and diorite belt (sensu Hanžl & Melichar, 1997) outcrops in the central part of the massif between two granodiorite complexes. Boundaries between rocks could be easily identified in this area. The metabasite zone consists mostly of low metamorphosed basalt and rhyolite dyke. There is the most common types of rock diorite with small bodies of serpentinite in the diorite belt. There is also some special microgranite on the boundary between metabasite zone and diorite belt found by Hanžl & Hrdličková (2011). Anisotropy of magnetic susceptibility (AMS) method was used to try to explain the tectonic relations between rocks in this area. The most frequent fabric has strike of magnetic foliation planes in NE–SW direction with steep dip oriented mostly to the NW and magnetic lineation developed in N–S directions (Figure). That trend can be recognized across all the studied area. That could be a proof of sinistral strike slip in Brno massif described by Hanžl & Melichar (1997). There was also used an analysis of temperature dependence of magnetic susceptibility. This method showed that all fabrics in all rocks in this area are essentially controlled by magnetite with a very small contribution of pyrhotite and hematite.
