FORC diagrams of bulk rock samples and mineral separates. All diagrams are calculated using a smoothing factor of 3. (a) Sample that was successful in the paleointensity experiments showing a narrow horizontal ridge along Hu = 0. (b) Sample that revealed a low NRM/TRM in the paleointensity experiments showing a concentrated peak. (c) Plagioclase crystal showing a narrow horizontal ridge along Hu = 0. (d) Olivine crystal showing a concentrated peak.
