Hi David,
I have described the occurence of Ms-Chl-Cld-Bt-Crd-Grt and
Ms-Chl-Cld-Bt-crd-And in the St-Guiral contact aureole (South-eastern part
of the French Massif Central). Only one sample of the begining of the outer
aureole contain these assemblages. You will find in attached documents the
photos of these assemblages. The photo-1 shows crd-and-bt-grt (+ ms, + chl
which were analysed). The cld is very small and is included in the crd knots
and is also found in the matrix. The photo-2 shows details from the same
sample.
My work was published in the French Geological Society Bulletin (BSGF). Here
is the reference :

Best regards,
Khalid.
