Abstract

An Illite/Montmorillonite mineral found in a porphyritic rock of Alpe di Siusi has an I/M ratio of 80:20. Introducing proper chemical parameters in a Q-Mode program of sixty-six Illites and Illite/Montmorillonite from the literature suggests the possibility of distinguishing Illites from Illite/Montmorillonite.

Résumé

Résumé

Un minéral Illite/Montmorillonite trouvé dans une roche porphyrique des Alpes de Siusi possède un rapport I/M de 80/20. En introduisant les paramètres chimiques convenables dans un programme en Q-Mode relatif à 66 Illites et minéraux Illite/Montmorillonite, d'après la littérature, on suggère la possibilité de distinguer l'Illite des minéraux Illite/Montmorillonite.

Ein Illit/Montmorillonit-Mineral aus einem porphyritischen Gestein der Seiser Alpe hat ein I/M-Verhältnis 80:20. Die Einfuhrung von geeigneten chemischen Parametern von 66 in der Literatur beschriebenen Illiten und I/M-Mineralien, verauläisst die Moglichkeit Illiten aus I/M-Mineralien zu unterscheiden.
