Temperature variations of magnetic susceptibility in rocks of the KTB pilot borehole and its vicinity (German part of the Bohemian Massif) and their geological and geophysical implications

  Abstract

The temperature variation of magnetic susceptibility of specimens selected from the KTB pilot borehole (German part of the Bohemian Massif) and sampled in the vicinity of the borehole were investigated by means of the CS-2 Apparatus and KLY-2 Kappabridge. The purpose of this investigation was to identify the minerals that carry the magnetism of the rocks under conside-ration. In weakly magnetic rocks the rock susceptibility is carried mostly by paramagnetic minerals (biotite in gneisses, hornblende in amphibolites) and only subordinately by magnetite. In strongly magnetic specimens the main contributors to the rock susceptibility are pyrrhotite and magnetite.
