Il est commode d’introduire la notion de «convergence métamorphique». [...] le même épisode thermique peut transformer une diorite(de façon rétrograde) et une marne(de façon prograde) en des roches indifférenciables l'une de l'autre-de deux directions opposées, l'assemblage minéralogique magmatique et l'assemblage sédimentaire «convergent» vers le même produit métamorphique. 1, record 1, French, - convergence%20m%C3%A9tamorphique
