La notion de variation chimique tend à se substituer à celle d'apport magmatique dont la réalité n'a jamais été démontrée. Plutôt que d'apports, il s'agit d'échanges d'éléments, de remplacement d'une molécule, d'un atome ou d'un ion par un autre, définition même de la métasomatose. 10, record 1, French, - m%C3%A9tasomatisme
