L'Ar étant un gaz rare, il diffuse facilement dans les minéraux, et le système a tendance à se rouvrir en particulier par diffusion en bordure des minéraux. Pour s'affranchir de ce problème, on effectue en général au cours de l'analyse un chauffage par paliers. Le gaz libéré est analysé à chaque palier, et un âge est calculé pour chaque fraction. Si le système ne s'est ouvert qu'en bordure de grain, les âges obtenus sur les premiers paliers seront «jeunes», mais les derniers paliers donneront tous le même âge appelé «âge plateau». 3, record 1, French, - %C3%A2ge%20plateau
