The orientation-distributions of AMS and AARM ellipsoids are non-coaxial in
the Kapuskasing Zone granulites. AARM is due to the preferred orientation
of magnetite which mostly postdates the silicate fabric. The AMS orientatio
n-distribution combines susceptibility anisotropies of magnetite and the si
licates. Whereas heating does not increase the bulk susceptibility, it does
improve the definition of the orientation-distributions of both AMS and AA
RM. However, the orientation-distribution of AARM is most enhanced and ther
efore post-heated samples emphasize the magnetite subfabric. Thus, heating
does not clarify the interpretation of the silicate fabric in this study. H
owever, it does change the samples' AMS fabric in such a way as to reveal t
he magnetite subfabric which can only otherwise be detected by more tedious
AARM measurements.
