Abstract (in english)
   Granitoid plutons of the Bohemian Massif have been studied from the point of view of their structural position with respect to the geophysical fields and to the depth of the Moho. These plutonic bodies occur mostly above the slopes between the elevations and depression of the Moho-relief. The pre-Variscan plutons occur predominantly within the positive zones of the regional gravity field (indicating a decrease of the thickness of the upper part of the Earth's crust). Of the Variscan plutons, the younger ones are located in regional gravity depresion zones of regional positive gravity anomalies and the negative ones. Another structural position show durbachite massifs and some small granitoid intrusions which are controlled by deep-seated faults. The regional anomalous geomagnetic field shows mostly similar relationship to the granitoid plutonism as does the gravity field. The exceptions (e.g. in the Krušné hory Mts. area) show differences in the interior structure of the upper crust
