Abstract (in english)
   Experimental results of pressure-induced changes in mean magnetic susceptibility of rock samples from the main KTB borehole are reported. It was found that susceptibility values of rocks from depths between 5200 and 7000 m show unstable behaviour upon application of pressure, showing an increase in susceptibility of 20 to 120 %.
