La méthode dite potassium-argon pose des problèmes plus redoutables : le potassium 40, isotope radio-actif de période 13.108 années, se décompose de deux manières: a) en calcium 40 [...] b) en argon 40. Il s'agit malheureusement d'un gaz qui s'échappe du réseau. Il est remarquable de constater que les feldspaths, à réseau de charpentes, donnent toujours un âge plus faible que les biotites, à réseau de plans: l'argon s'échappe plus difficilement de ces dernières. 6, record 1, French, - m%C3%A9thode%20potassium%2Dargon
