Synthesis of intermediate K-NH4 dioctahedral micas from kaolinite had been carried out using two chemical systems K2O-(NH4)2O-Al2O3-SiO2-H2O (1) and K2O-(NH4)2O-Al2O3-SiO2-HCl-H2O (2). We have used variable NH4:K ratios, with the aim of testing the e

The aim of this paper is the characterization of pure tobelite synthesized in the system (NH 4 ) 2 O-Al 2 O 3 -SiO 2 -H 2 O, which is a first, indispensable step for accurately interpreting the data obtained in more complex chemical systems. Tobelite

Talc-phengite intergrowths were identified in epizone rocks from the Beni Mezala unit (Internal Zone of the Rif). These rocks show the non-common assemblage quartz-K-feldspar-albite-phengite-talc-vermiculite-chlorite/vermiculite mixed-layers. Althoug

A study of mineral assemblages obtained experimentally from kaolinite was carried out by X-ray diffraction and transmission/analytical electron microscopy in the systems K2O-MgO-Al2O3-SiO2-H2O-HCl, Na2O-MgO-Al2O3-SiO2-H2O-HCl, and Na2O-K2O-MgO-Al2O3-

A detailed characterization of the mineralogy corresponding to the low-grade diagenetic-metamorphic sequence of the clastic rocks from the Beni Mezala antiform has allowed the processes implied in their origin to be stablished, integrating them in th

We have conducted a detailed chemical, structural, and spectroscopic study of the alteration products of cordierite in meta-rhyolites from the Ceuta zone (Rif belt) with the aim of determining the nature of the products, the main stages of cordierite

Al–Ni and Al–Co lizardites have been synthesized at hydrothermal conditions. The two phases display different morphologies: thin, dominantly curved platelets (Al–Ni); and stacks of very thin platy particles (Al–Co). The X-ray diffraction and

Al-lizardite has been synthesized under hydrothermal conditions (200ºC). Morphologically, Al-lizardite consists of thin platy particles ~400 Å wide and ~150 Å thick. Structurally, the X-ray diffraction patterns indicate that the 2H2 polytype is do

Fe 3+ , Ga 3+ and Cr 3+ substituted kaolinites had been synthesized at hydrothermal conditions (200 °C), starting from very disordered ground kaolinite and Fe 3+ - Ga 3+ - and Cr 3+ -bearing solutions. The synthetic kaolinites showed a roughly bimod
