Release of potassium by extraction with solutions containing sodium tetraphenyl boron or by leaching with 0·1 N barium chloride seemed to be related to the nature of the mica layers in the interstratified minerals studied. The rate of potassium release was lower when the calculated Si/AlIV ratio of the mica component layers resembled muscovite and higher when this ratio was intermediate between muscovite and pyrophyllite. This supported a recent hypothesis that the composition and structure of the mica component layers may vary in different interstratified minerals of similar total chemical composition.

Résumé

Résumé

Dans les minéraux interstratifiés observés, la libération de potassium par extraction avec des solutions contenant du tétraphényl-bore de sodium, ou par lavage avec du chlorure de barium 0,1N semble être en relation avec le nature des couches de mica. Le taux de libération du potassium diminue lorsque le rapport Si/AlIV calculé des couches de mica ressemble à celui de la muscovite, et augmente quand ce rapport est intermédiaire entre celui de la niuscovite et de la pyrophillite. Ceci appuie une récente hypothèse selon laquelle la composition et structure des couches de mica peuvent varier dans des différents minéraux interstratifiés de composition chimique totale similaire.

Kurzreferat

Kurzreferat

Die Freigabe von Kalium durch Extraktion mit Natriumtetraphenylbor enthaltende Lösungen oder durch Auslaugen mit 0,1 N Bariumchlorid stand scheinbar in Beziehung zu der Natur der Glimmerschichten in den zur Untersuchung gelangenden zwischengelagerten Mineralen. Die Geschwindigkeit der Kaliumfreigabe war niedriger wenn das errechnete Si/AlIV Verhältnis der Glimmerbestandteilschichten dem Muskowit ähnelte und höher wenn dieses Verhältnis zwischen Muskowit und Pyrophyllit lag. Das bekräftigt eine vor kurzem aufgestellte Hypothese, wonach die Zusammensetzung und das Gefüge der Glimmerbestandteilschichten in verschiedenen zwischengelagerten Mineralen ähnlicher chemischer Gesamtsusammensetzung veränderlich sein kann.

Резюме

Резюме

Экстракция калия растворами, содержащими натриевый тетрафенил-бор, или растворами 0,1 N хлорида бария, по-видимому, зависит от природы слюдяных слоев изученных смешаннослойных минералов. Скорость извлечения калия была ниже, если вычисленное отношение Si/AlIV слюдяного компонента было близким к мусковитовому; при значении указанного отношения между мусковитовым и пирофиллитовым скорость извлечения калия была выше. Это подтверждает недавно сформулированную гипотезу, согласно которой состав и структура слюдяного компонента слоев может варьировать в различных смешаннослойных минералах одного и того же валового химического состава.
