Summary
The stress sensitivitiesS x andS R of susceptibility and remanence for titanomagnetite-bearing rocks are calculated in terms of magnetostriction constantsλ 100 andλ 111 and anisotropy constantsK 1,K 2 of the magnetic minerals.S x andS R are represented by quite different algebraic expressions but happen to have comparable numerical values over the whole range of titanomagnetite compositions. Both increase strongly with titanium content. This leads to more optimistic calculations of tectonomagnetic effects than with the previously assumed stress sensitivity for pure magnetite.
