[...] 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

Dans les roches favorables, l’anatexie ne débute que pour une intensité suffisante du métamorphisme (l’anatexie est parfois appelée ultramétamorphisme) : la fusion des roches métamorphiques se produit [...] à une température de l’ordre de 680 °C [...] 4, record 2, French, - ultram%C3%A9tamorphisme

D'après les sources de langue anglaise, l'ultramétamorphisme est un concept plus général que l'anatexie, puisqu'il s’agit de processus dans lesquels s’inscrit la fusion anatectique ou anatexie. Le lien entre l'anatexie et l'ultramétamorphisme semble en être un de cause à effet. 3, record 2, French, - ultram%C3%A9tamorphisme
