CONT

Le polymétamorphisme se traduit [...] par une minéralogie complexe et très particulière et par une géochimie inusuelle, rassemblant des éléments qui ne se rencontrent pas ensemble dans les minéralisations dont l'histoire géologique est plus simple [...]

CONT

Les polymétamorphismes comportant une phase rétrograde sont généralement incomplets, c'est-à-dire qu'ils présentent des témoins non rétromorphosés du fait d'une quantité insuffisante d'eau.
