Abstract
Non-ferromagnetic minerals constitute what is called the rock matrix, whose susceptibility (K1) is directly accessible using only high magnetic fields. Measurements on minerals and a wide range of rock types show that K1 is mainly due to paramagnetism and hardly exceeds 10−3 SI, with an anisotropy degree (P) less than 1.35. Different methods to estimate the role of the matrix component in low-field susceptibility (K) and its anisotropy include petrological and chemical analysis, evolution of P vs K, low temperature studies and comparison of K with remanent magnetizations.
