Abstract

Biotite was altered by boiling in 0.2 M A1C13 solution, and the products were examined by X-ray powder and single-crystal diffraction, chemical analysis and thermogravimetry. The altered material is a 14 Å clay mineral with hydroxy-Al interlayers. It has a stacking sequence characteristic of vermiculite and its silicate layers are similar in chemical composition to trioctahedral vermiculite. The results of extracting the interlayer material with sodium citrate solution, X-ray examinations after heating and thermogravimetry show that the interlayer material is composed of Al associated with OH and H2O. The chemistry and kinetics of the alteration reaction and the orientational between the altered and original biotites are also discussed.

Résumé

Résumé

Une biotite a été altérée à l’ébullition dans une solution A1C13 0,2 M et les produits résultants ont été étudiés par diffraction X sur poudre et sur cristal unique, par analyse chimique et thermogravimétrie. Le matériau altéré est un minéral argileux à 14 Å contenant de l’hydroxy-Al interfeuillet. Il a une séquence d’empilement caractéristique de la vermiculite et les feuillets silicatés ont une composition chimique semblable à celle d’une vermiculite trioctaédrique. L’extraction du matériau interfeuillet par une solution de citrate de sodium, les examens aux rayons X après chauffage et la thermogravimétrie, montrent que le matériau interfeuillet est composé d’Al associé à OH et H2O. On discute également de la chimie et de la cinétique de la réaction d’altération et de la relation existant entre l’orientation des biotites altérées et originelles.

Kurzreferat

Kurzreferat

Biotit wurde durch Kochen in 0,2 M AlCl3-Lösungen umgewandelt und die Umwandlungsprodukte mit Hilfe der Pulver- und Einkristallröntgenbeugung sowie der chemischen Analyse und der Thermogravimetrie untersucht. Das umgewandelte Material besteht aus einem 14 Â Tonmineral mit Hydroxo-Al-Zwischenschichten. Es besitzt eine für Vermiculit charakteristische Schichtabfolge und seine Silicatschichten ähneln in der chemischen Zusammensetzung denen des trioktaedrischen Vermiculits. Die Ergebnisse einer Extraktion des Zwischenschichtmaterials mit Na-Citratlösung, die röntgeno-graphische Untersuchung nach Erhitzung und die Thermogravimetrie zeigen, daß das Zwischenschichtmaterial aus einer Verbindung von Al mit OH und H2O besteht. Die Chemie und Kinetik der Umwandlungsreaktion sowie die Beziehungen in der Verteilung der Gitterionen zwischen umgewandelten und ursprünglichen Biotiten werden ebenfalls diskutiert.

Резюме

Резюме

Варкой в растворе 0,2М А1С13 изменили биотит и полученный продукт исследовали методом рентгеновских порошкограмм, дифракцией одного кристалла, химическим анализом и термогравиметрией. Измененный материал является глинистым материалом 14 À с прослойкой гидрокси-Al. Он имеет характеристику последовательной столбчатой укладки вермикулита и его слой силиката подобен по химическому составу триоктаэдральному вермикулиту. Результаты экстрагирования прослоенного материала раствором лимоннокислого натрия, рентгенографических исследований после нагревания и термогравиметрии показывают, что прослоенный материал состоит из AI ассоциированного с ОН и Н20. Также рассматривали химию и кинетику реакции изменения и ориентационное соотношение между измененным и исходным биотитами.
