These intermediate aureole fabrics are divergent from relict bedding but likely to have composite origins related to tectonic stresses and emplacement of the pluton.
Narrow contact-metamorphic aureoles imply emplacement at a high level.
Elsewhere, acquired magnetizations continue to climb in higher fields, indicating that hematite is a significant ferromagnetic component in both pluton and aureole.
In the neighbourhood of the granitoids a sharp contact aureole is present.
Along the southwest margin a contact aureole has been preserved at the base of the granite.
The inner part of this aureole is characterized by migmatites, whereas andalusite-sillimanite-garnethornfelses have developed in the outer part.
The presence of andalusite in contact aureoles reflects shallow crustal levels of emplacement.
Veinlets and disseminations of quartz + sericite + epidote + chlorite + pyrite + pyrrhotite + chalcopyrite are locally developed in the aureole.
