Complex mid‐crustal flow within a growing granite–migmatite dome: An example from the Variscan belt illustrated by the anisotropy of magnetic susceptibility and fabric modelling

Popis výsledku v původním jazyce

This study describes anisotropy of magnetic susceptibility (AMS) of migmatites associated with crustally derived granites of the Pelhřimov core complex, Bohemian Massif. In combination with numerical modelling, we use this case example to discusssome of the general complexities related to interpreting flow patterns of anatectic lower and middle crust from magnetic fabric during growth of metamorphic domes. Magnetic lineations, reflecting tiling or zone axis of magnetically oblate grains, commonly tend to develop along the principal stretching direction. Our fabric modelling,however, shows that a lineation may also develop at a high angle to the overallflow (tectonic transport) direction as a relict of a pre‐existing fabric or due to a component of core complex axis‐parallel stretching and may be maintained for a significant period of time.
