Rock-magnetic results. a Anhysteretic remanent magnetization susceptibility (κARM) plotted against volume magnetic susceptibility (κ). b The Day plot used selected specimens from Core M and Core I (Day et al. 1977). Mrs saturation remanent magnetization, Ms saturation magnetization, Hcr remanent coercivity, Hc coercivity. SD, PSD and MD indicate single domain, pseudo-single domain, and multidomain fields, respectively, with the limits given by Dunlop (2002)
