Small diamagnetic anisotropy, (Δ_X)_<DIA>, on the order of 10^<-9> to 10^<-9> emu/g was detected for four silicates by the use of the field-induced harmonic-oscillation method in the high temperature region. The measured Δ_X-T relations were effective to separate the Δ_X component caused by the paramagnetic impurity ions. The obtained maximum (Δ_X)_<DIA> values between two magnetic principal axes are (2.1±0.1)×10^<-9> emu/g [b-a axes] for orthoclase, (3.5±0.1)×10^<-9> emu/g [b-a axes] for petalite, (0.8±0.1)×10^<-9> emu/g [a-c axes] for scapolite and (3.8±0.1)×10^<-9> emu/g [a-c axes] for apophyllite. The (Si,Al)O_4 tetrahedral frameworks composing the crystal structures of the silicates are considered to be the origin of the observed (Δ_X)_<DIA> values.
