Abstract

XRD, DTA, IR, chemical and electron microscopic data are presented for three specimens of regularly interstratified 25 Å minerals from Roseki deposits in Japan. The layer charges of these dioctahedral mica-smectites originate mainly from tetrahedral Al-for-Si substitution. The non-expandable interlayers are occupied by relatively large amounts of Ca and K as well as Na. The expansion characteristics of the expandable interlayers are montmorillonitic in spite of the beidellitic composition of the 2:1 layers.

Resume

Trois échantillons d'un minéral phylliteux à interstratifications régulières (25 Å) et provenant des dépôts de Roseki (Japon) ont été étudiés par diffraction des rayons X, analyse thermique différentielle, spectroscopie infrarouge, analyse chimique et microscopie électronique. Les charges des feuillets de ces mica-smectites di-octaédriques sont dues essentiellement aux substitutions Si par Al en positions tétraédriques. Les espaces inter-feuillets non gonflables sont occupés par des quantités importantes de calcium et de potassium aussi bien que par du sodium. Les caractéristiques de gonflement des interfeuillets gonflables sont du type montmorillonite en dépit de la composition de type beidellitique de ces feuillets 2: 1.

Kurzreferat

Kurzreferat

Röntgenographische, Differential Thermoanalysen, IR-spektrometrische, chemische und elektronenoptische Daten werden für drei Arten von regelmäßig wechselgelagerten 25 Å Mineralen aus Roseki Lagerstätten in Japan angegeben. Die Schichtladung dieser dioktaedrischen Glimmer-Smectite hängt hauptsächlich von der tetraedrischen Substitution des Al gegen Si ab. Die nicht expandierbaren Zwischenschichten sind mit relativ großen Beträgen an Ca, K und ebenso Na besetzt. Die Aufweitungscharakteristiken der expandierbaren Zwischenschichten sind montmorillonitisch, trotz der beidellitischen Zusammensetzung der 2: 1 Schichten.

Resumen

Resumen

Se presentan datos de DRX, DTA, IR, microscopia electrónica y análisis químico de tres muestras de minerales interestratificados regulares de 25 Å de espaciado basal, procedentes de los depósitos de Roseki (Japón). La carga laminar de estos minerales dioctaédricos mica-esmectita procede principalmente de sustituciones de Si por Al en la capa tetraédrica. El espacio interlaminar, hinchable, está ocupado por cantidades relativamente grandes de Ca y K así como de Na. El tipo de hinchamiento es característico de la montmorillonita, a pesar de que la composición química de la lámina corresponde a una beidellita.
