Abstract: Iron and silicon in various proportions are the major components of the newly formed hydrothermal sediments in the Atlantis II Deep, Red Sea. Iron-rich 2:1 phyllosilicates with morphologies ...
Abstract: Mixed layering of illite-smectite was studied both experimentally, by using high-resolution transmission electron microscopy (HRTEM) and analytical electron microscopy (AEM), and theoretical...
Abstract: Synthetic goethites studied by high-resolution thermogravimetry (HRTGA) show variability in surface characteristics and structural stability as a function of aging conditions. Goethites were...
Abstract: High-resolution transmission electron microscopy (HRTEM) examinations have indicated that three types of surface layers may exist in natural kaolinite crystals. Type 1 has the expected 7-侌 s...

Abstract: Unmodified and surfactant-modified clinoptilolite-rich tuff (referred to here as 揷linoptilolite? and muscovite mica were examined with tapping-mode atomic force microscopy (TMAFM) and high-r...
The coordination environment of Ti in eight Ti-bearing glasses of the Na Si-Na,Ti y4 ;:join (NTS) and in six ATY2 glasses (A20Ti02.2Y02, with A =Na, K, ~r Rb andSi or Ge) was determined using high-re...
High-resolution neutron powder diffraction was used to study phase transitions in theleucite phases of KAlSi206, RbAlSi20", CsAlSi206, and KFeSi206. Thetemperature-depen-dent structural behavior invol...
Fine clays (<0.1 祄) extracted from an acid soil developed in a granite saprolite from the Massif Central, France, were characterized by X-ray diffraction (XRD) using a curve decomposition program, and...
The mode of growth of authigenic, lath-shaped illitic particles has been investigated using field emission scanning electron microscopy (FESEM) and high resolution transmission electron microscopy (HR...
High resolution transmission electron microscopy (HRTEM) have been performed on dispersed portions of one R > 1 and two R3 illite/smectite (I/S) samples from Silurian K-bentonites. R > 1 sample was st...
Several soil and reference smectites and vermiculites and one reference illite were examined by high-resolution transmission electron microscopy (HRTEM) to decipher the nanostructure and layer charge ...
Bulk mineralogy of the terrigenous fraction of 99 samples from ODP Site 722 on the Owen Ridge, western Arabian Sea, has been determined by x-ray diffraction, using an internal standard method. The sam...
Examination of two volcanic and two precipitated allophanes by solid-state NMR, thermal analysis and X-ray powder diffraction shows three of the samples to contain structural features similar to both ...
Unheated natural mixtures of manganite and secondary pyrolusite, from the same lateritic manganiferous sequence, were studied in different orientations by high-resolution transmission electron microsc...
