“…In deformed rocks, the potential of susceptibility anisotropy as a strain gauge has received a lot of attention (e.g., Owens, 1974;Singh et al, 1975;Hrouda, 1976;Wood et al, 1976;Kligfield et al, 1977;Goldstein, 1980;Rathore et al, 1983;Henry and Daly, 1983;Borradaile, 1987;Cogné and Perroud, 1988;Hirt et al, 1988;Ruf et al, 1988;Pearce and Fueten, 1989;Kodama and Sun, 1990;Housen et al, 1995). The main reasons for this application are: (1) the relative ease by which the AMS ellipsoid can be established; (2) the sensitivity of the method to weakly developed rock fabrics; and (3) that essentially all rocks are magnetically anisotropic and therefore magnetic anisotropy offers a nearly universally applicable method to analyze deformation state of rocks, as opposed to the much smaller population of samples that may contain other strain indicators.…”
