Dear Ronan,
Regarding your request, there is one case of contact metamorphic
amphibolites in the Rhodope zone, Northern Greece, which I have seen and
described myself, in the framework of my PhD thesis. These rocks are
partly
to completely transformed into cpx-opx plag 'hornfelses'. In the field
one
can observe still relics of the original amphibolite in form of a few
cm-large 'patches' in a greenish (cpx dominated) rock. These
amphibolites
occur together with many other regional metamorphic rocks (e.g marbles,
ultramafics, metapelites), which were also affected by contact
metamorphism
caused by a granodiorite intrusion. There is some description, mineral
chemistry, met. conditions etc. in my thesis, which you may find through
Laurent Jolivet / Bruno Goffe (ENS, Paris). Bruno Goffe should have it.
I
hope that helps.
cheers
Anthi Liati
