The diamagnetic anisotropy (△_X)_<DIA> derived from the individual bonding orbitals of the silicate [TO_4] networks is estimated from the observed results on a-quartz [Si0_2], orthoclase [KAISi_30_8] and apophyllite [Ca_4KF(Si_40_<10>)2 , 8H_2O] . The (△_X)_<DIA> Value of individual chemical bond was estimated to be -3.5 x 10^<-30> emu/mol, the uniaxial principal axis being parallel to the bond direction. The calculated results indicate that the bond direction is the magnetically unstable axis. This result is compatible with the observed and calculated distributions of electron density for the T-O orbitals, which are preferentially spread in the direction off the bond direction.
