[...] le magma basaltique injecté du dessous dans le sein de l'écorce continentale à la faveur de fissures volcaniques transmet aux roches encaissantes assez de calories pour les faire fondre. Cette fusion, cette «anatexie», rend d'ailleurs compte [...] de la genèse de nombreuses ignimbrites [...] 4, record 1, French, - anatexie

La limite supérieure du métamorphisme correspond à la fusion totale des roches. Celle-ci dépend fortement de l'hydratation du milieu, ainsi le domaine de l'anatexie (fusion partielle des roches) qui est limité par le solidus du granite [...], vient-il chevaucher le domaine du métamorphisme. 5, record 1, French, - anatexie

La minéralisation uranifère se serait formée durant la phase de tectonique d'extension qui a suivi la fin de la subduction; les solutions minéralisatrices ont pu être générées par une anatexie de la croûte profonde [...] 6, record 1, French, - anatexie
