摘要：
Investigations on electrical conductivity of biotite gneisses and garnet amphibolites from the KTB borehole (3500-3800 m) were carried out in two laboratories under different physical conditions. Gneisses exhibited higher anisotropy of electrical conductivity than amphibolites. The explanation of the observed anisotropy of electrical conductivity can be found mainly in the structural features (in particular, the foliation fabric) of these rocks. The results indicate the persistence of anisotropy of electrical conductivity to high temperatures (at least 1000 degrees C).
